There's a slightly improved version of the Dan A4 on Kickstarter again:

https://www.kickstarter.com/projects/33753221/dan-cases-a4-sfx-v2-an-ultra-compact-sff-case

I figure it's the only reliable way to get it as the first version ones sold through retailers have been gone almost instantly. Dan isn't going to make any more after this, apparently he has a new project he'll be pursuing next.

If the case has enough room for the stock cooler, you don't need an aftermarket one for your Ryzen. The case allows for CPU coolers of up to 140 mm height, I don't know how large the boxed AMD cooler is, though.

The X370 chipset is more expensive, while the additional stuff you get over B350 mostly isn't used on mini-ITX boards anyway, like more PCI-e slots that actually use the additional lanes or SLI support. I think it also has fewer native USB 3.1 Gen 1 ports, not sure how much that affects you or whether they make up for it with third party controllers on the mainboard. Here's a review that covers both mainboards in one article: https://smallformfactor.net/reviews/motherboards/fatal1ty-asrocks-x370-ab350-gaming-itxac-motherboards-reviewed

Connecting your PC with a modern OS to a TV over HDMI is no pain at all. I built a living room PC based on the Fractal Design Node 202, it's a similar setup with a GTX 1050 Ti and I didn't have to set up anything to connect my fairly ancient Toshiba TV to it.

Dan is working on another case, this time slightly larger than the A4:

https://hardforum.com/threads/dan-c4-h2o-a-water-cooled-sff-case.1944458/

It's still intended for SFX PSUs and ITX mainboards, but uses a fixed riser (the 3M one for the A4 is expensive and slows down manufacturing) and adds a bit more room (2 liters more) for water cooling parts and case fans. It also has a few more front panel connectors.

I might sell my A4 for this, eventually. The additional size is no big deal to me and you gain some more flexibility for quieter/better cooling. [edit] Nevermind, the new one only has 60 mm CPU clearance, not 70, which limits it to water cooler or puny air ones like the L9i/a and Cryorig C7 again (Noctua eg. has two slightly thicker coolers which are 65 and 70 mm :()

The other part I don't like is that video cards are still limited to 2 slots. All the good custom designs for eg. the GTX 1080 Ti (and Vega :lol:) use 2.5 slot coolers at least, so being restricted to lower end GPUs or lovely blowers (or bad custom coolers like the MSI Armor) is not great.

Yeah it looks like the self-imposed restriction of staying under 10 liters and the decision to save cost and manufacturing time by going for a fixed riser instead of the flexible 3M one means the case is still nearly as restrictive overall as the A4.

The additional room does buy you better watercooling, if you're looking for that (the A4 V2 has room for only the Asetek 545LC and you sacrifice the front USB for it). And lower overall cost, which is probably the main reason he's doing it.

That depends on what you mean by "nicest". The Ncase M1 certainly has a lot more flexibility when it comes to cooling thanks to the conventional setup - the main challenges of the really small SFF cases are airflow and clearance for CPU coolers. The M1 lets you add a pretty large tower cooler if you want to, and you can add tons of case fans for GPU cooling too. Really small cases (RSFF?) usually only have room for 2.5" drives, but as you're approaching mATX sized cases there should be plenty of options.

It's still possible to make a cool and quiet PC with tiny cases, you just have to have the right parts eg. if you want to run a Core i7 k-CPU in a Node 202 you pretty much need to delid it and MacGyver the existing low profile CPU coolers to be more efficient or powerful (eg. zip-tie 120mm fans onto them or take the LP53 apart for its copper heatsink), and either pick a cooler GPU or undervolt a hotter one. And cables are a pain in all of them, my Dan A4 is a mess due to the power cables out of the SF450 PSU and I'm really considering custom cables for it.

I wouldn't say that. SFF systems with high end components require tweaking either way, and "overclocking" boards allow that. Both ways. It's just that the defaults are tuned towards higher power use/temperatures to get a bit more performance out of even non-overclocking parts (like non-K CPUs). Unfortunately this is at odds with a basic SFF setup where you don't have room for excessive tower coolers or multiple AiOs and lots of options for case fans for airflow.

But I'm glad it's working now. I probably have to repaste my delidded 7700k, it goes up to 90°C in Prime95 and I don't think it should (it's fine in games with 70°C though).

Speaking of which, what is the go-to cooler for a Dan A4 anyway? I'm assuming Cryorig C7 or Noctua L9i? Kinda really want to do a A4 build right now, but I'm not really sure how to cool a 8700k in something that small.
C7 or some DYI solution, the L9i is made for much less powerful CPUs - a 8700k will probably reach throttling temperatures in no time if you use a stock L9i on top of a 8700k with default settings (ideally on a mainboard with multicore enhancements on :v:).

You can put a different fan on top the L9i heatsink (it's tiny so you can fit a 25mm fan on it) or use a 14 or 15 mm Noctua (eg.) fan on top of a better heatsink like that of the C7 or LP53.

People who run that sort of CPU also delid or undervolt. A 10-20 degree difference from delidding is huge.

Blowers are cheaper and easier to fit in (most 3rd party designs for the GTX 1080 Ti use 2.5 or 3 slot coolers which don't fit the A4) which I assume is a big part of why they're used in the A4. They're not necessary for cooling reasons, they actually get hotter and louder, as usual. Since the video card sits next to the side panel with ventilation holes in the A4 (unless you use the window edition), a 2-slot high-end open air card will just blow most of the hot air through those instead of into the case.

The real challenge is going to be the CPU/VRM cooling, though.

How insane is it to use a dual fan type of GPU in the Dan Case? I've got the EVGA 2080 on pre-order to go into my ATX build now, but sometime after New Year's I'd like to upgrade my CPU which means a whole new motherboard and I've been wanting to go ITX for a while. Figure I should go all in when I do. If cooling is going to be awful in the Dan Case though, I would consider the Ncase M1. It's not much bigger but it looks like it uses a more traditional layout that would be better for an open fan GPU if I understand correctly?
Not at all.

Cards with open air coolers have issues in cases which trap the hot air in compartments with limited or no airflow (eg. the Fractal Define Nano S). This is not the case in the Dan A4 without the window panel - GPU fans will blow most of the hot air out of the side panel ventilation holes (and somewhat heat up the side panel itself).

The main restrictions in the Dan A4 for high-end builds are GPU size (height especially, since many manufacturers use 2.5- or 3-slot open air coolers for their fastest cards) and CPU cooling (because of the 48mm height limit). People put modern 6- and 8-cores in it but they're not boosting as high or for as long as in a bigger case.

Corsair because the last time I was reading reviews the SF-line was better than the competition, and there are slightly better Platinum versions now (these apparently come with individually sleeved cables which should make them easier to install than the super stiff ribbon cables the original Gold versions use).

A bigger ITX case is not "better" but it can have soundproofing and room for quieter cooling parts that take more room, but the size difference is quite enormous next to a Dan. The Dan A4 is great if you want your computer to be as small as possible while using standard parts (vs. something like the S4 mini that is even smaller but needs short GPUs and notebook-like PSUs), but the size limits you nonetheless.

Since the A4 doesn't use any soundproofing it's at most roughly as loud as the parts in it under full load - so it depends on what you perceive as "loud" and what parts are in it. While it's possible to build a PC with the new i9 9900k and a founder's edition RTX 2080 Ti in a Dan A4, it's not going to be very quiet under full load because you can't use any huge air cooler or AIO, and most GPUs 1080 Ti and faster that are also reasonably quiet use 2.5 or even 3 slot cooling, which is too large for the A4. A setup with efficient mid-range components with an emphasis on quiet parts will not be "loud" to most people, though. I have an A4 with a i7 7700k and a GTX 1050 Ti, when it's idle it's completely silent but in stress tests the little 92mm fan on the tiny cooler runs at 2500rpm - very audible, but not loud in an annoying way to me. In games it's somewhere in the middle, audible but not loud by any stretch - however, I don't have it sitting right next to my ear on a desk.

Either way, a Ryzen 7 2700 comes on a socket that AMD plans to keep for about two more CPU generations and it's alright to cool with eg. a Noctua L9a-AM4 in a Dan. You can also do the 2700X in a larger case with larger coolers. Or start with a Ryzen 5 2600 (6 cores) and upgrade the CPU again later. Either is not as fast as the new Intel 8-core i7/i9 but they're also much cheaper, and with some modern games using all the cores they can (eg. Battlefield, Ubisoft games), I'd say it's more "future-proof" to get a low priced 8 core CPU than a higher clocked 4- or 6-core part, unless you plan to play e-sports titles at high refresh rates or a lot of old, badly threaded/CPU-bound games like most MMOs.

32GB of RAM is the "future proof" option, but keep in mind mini-ITX mainboards usually only have two RAM slots so you'd have to buy two 16GB sticks which cost more than 4x 8GB would.

The founder's edition RTX cards all fit into a Dan A4 but they don't shut off their fans while idle yet (to be fixed by a driver later, according to Nvidia) and they're generally a bit louder than the massive 3-slot coolers on third party cards. So, for playing in 1920x1200 for now, I would get a good dual-slot open air GTX 1070 Ti, GTX 1080 or RTX 2070 for a Dan, or 2.5/3-slot parts in a larger case that supports the GPU's size. A GTX 1080 Ti/RTX 2080 or even RTX 2080 Ti could be an option but they're overkill for your current monitor in games. If you want more performance just for deep learning, go all out on a RTX 2080 or 2080 Ti :v:

It sounds like the a4 sells out everything to be as small as possible for standard parts. Does the next size up help noise any? Is that something like the ncase m1?
There are a few cases in between, also using PCIe risers to move the GPU, trying to be "console" sized eg. Those are as "bad". Someone on :reddit: (I think) made this picture:



As you can see the A4 is exceptionally small for having room for standard parts - the 50 mm CPU cooler clearance is really its biggest downside. It would only take about 1" more to fit much more potent coolers (eg. Noctua's NH-L9x65 or even NH-L12S) for cooler/quieter operation. The guy is making a slightly larger case - the C4 - which can take 2.5-slot GPUs so that's great, except CPU clearance is still a disappointing 62 mm (but there's room for larger radiators at least).

Most SFF cases aren't particularly soundproofed either (unlike, say, a massive ATX case like a Fractal Design Define R6), but the larger cases with a more standard layout (like the M1 or all the cubes) can end up quieter because you can use larger heatsinks/fans instead of small fans which have to work harder, and you don't have components sitting at the outside of the case next to perforated side panels in order to optimize cooling, like in the Dan. Again, the A4 is not a jet engine unless you build it like one, but it's also not going to be silent outside of Windows and the same hardware in a larger mini-ITX case has the potential of running quieter/cooler.

Basically fast/quiet/small, pick two.

E: Something like the H200i works too, but with 26 liters isntead of 7.2 (Dan A4) or 12.6 (Ncase M1) I hope it has much better compatibility with parts and much better thermals/lower noise - that's not very small anymore :v:

Just gonna shout out that even the NH-L12 just barely "works" on keeping a i7 8700 (non-K) cool.

I agree. Buying custom cables for the SFX PSUs are easily more expensive (even if you just buy the Corsair premium cable kit) than upgrading to the platinum PSU directly. Fitting the super stiff SF 450 cables was a pain in the rear end in my Dan, and it basically makes it impossible to fit a fan or AIO under the PSU in the v2 or v3 cases.

Yeah I'm looking forward to tests of that cooler. I wonder how much of an improvement it really is because this production variant of Dan's HSLP-48 project has its own set of limitations - they seem to be going for cosmetic "upgrades" that Dan had ruled out in his prototype testing, it's not using copper fins and while you can fit the wider heatsink, you need virtually nonexistent VLP RAM if you also want a larger fan, and even for the default setup you can't have RAM with even moderate height heatspreaders (which disqualifies all the RGB RAM for people who care about :catdrugs:).

The Nano S is pretty large for an ITX case so I wouldn't expect any issues, considering the case has room for a "standard" 2 intake/1 exhaust case fan + big CPU air cooler setup. I think the biggest challenge with that specific case is the clearance between GPU and an ATX PSU, a 2-slot GPU with open air cooler has no room to "breathe" - if you use a (eg. 600W) SFX PSU this won't be a problem, though.

In a smaller HTPC case, air cooling is harder because you generally don't have the clearance for powerful heatsinks and fans (but small enough AIOs for the really tiny cases don't really exist anymore, either).

Modern CPUs and GPUs all have the option to limit their TDP somehow, so even a tiny case could run a 9900k + RTX 2808 Ti, it just won't run them at turbo/boost clocks very long (or quietly, or possibly at all), and overclocking makes even less sense. In a large-ish ITX case, though, with enough room for 15 cm baby head CPU coolers? That's definitely possible.

I haven’t seen too many people talk about this, but is it possible to have a near silent (~30ish dB) air cooled SFF setup?
Note: Corsair sells ATX-SFX brackets too.

As for the quoted part, it's going to depend entirely on what hardware and settings are being used so that's probably why. Like the poster above who did a Dan A4 with a Cryorig C7 - they solved this for their own requirements by using a lower TDP CPU, undervolting and other tweaks. Using a different fan/cooler could be an improvement (the C7 fan is bad and on top of that, it adds noise in the A4 due to turbulence because it sits too close to the side panel), but someone who tries to run higher TDP parts and trying to overclock will have a different experience.

With your planned parts it *should* work with eg. a Noctua NH-D15(S) or NH-U14S (or comparably quiet alternatives), and a GPU with a good cooler (cheaper models often sacrifice cooling and run louder, due to smaller fans having to run faster on smaller heatsinks with fewer heatpipes, eg.) but it might require tweaks as well, eg. reduced CPU TDP and GPU power limit and undervolted parts allowing them to run cooler and fans to run slower.

So, Dan is changing the C4 case again.

He's considering a flexible case layout that can both accommodate the original stacked/sandwich setup as well as a classic setup similar to the Ncase M1. This flexible layout would mainly require an increase in width to 140 mm (with special angled power connectors) or 149 mm.

IMO this would make much more sense than the limited original design that only played well with AIOs and still had cooler/GPU size limits close to the A4. With the flexible setup you can fit up to a 3-slot GPU (width is going to be the limiting factor here) and bigger top-down or even small tower coolers (he mentions the Noctua C14 and U9S).

He also had someone from SFFLab over to test his C4 prototype and both said the original layout and size is a pain to build in, and even though the measurements would allow for custom loops and 2.5-slot GPUs those are basically impossible to fit.

In other news, EKL hosed up manufacturing of the Alpenföhn Black Ridge (the cooler that's loosely based on Dan's HSLP-48 project) and although it was released in late November, the fixed batch is still nowhere to be seen. Apparently it should come out towards the end of February but we'll see. I sent mine back before ever using it, because 5 out of 6 heatpipes were only barely soldered to the base plate.

E: Also, apparently Asetek is making a new compact AIO (replacement or upgrade to the 545LC) which should help in the A4 and other cases of similar size.

The common recommendation (by the guy who made the Dan cases, even) is to do like notebooks and set a long term power limit in your BIOS (eg. 95W) - a 2700X / 9900k can still use all 16 threads and run max clocks on some of them for a short while, but they get limited to lower (boost) clocks quickly if you use software that utilizes most threads to 100%. This will still make the 92mm fans on tiny heatsinks run at 2500 rpm or whatever, so it's going to be audible (even with Noctua fans), but you're not going to run into actual thermal throttling unless you run this 24/7 in a hot room.

In every day use and gaming you're not going to suffer much of a penalty compared to the default "TDP unlimited, MCE enabled" of a desktop board with baby head cooler, but it's obviously not going to be as fast, and the difference is more pronounced in something that uses all cores for a long time, like rendering or video editing. In raw numbers the CPUs with higher (default) clocks and more threads should still come out ahead. Everyone has to decide for themselves if that's worth the additional price of the faster CPUs.

that looks really cool, I just watched a video of somebody cramming an i7-8700k and a 2080 in one though and it was like... too hard. I'd be perfectly willing to live with a case twice that size to have it be quieter and not an impossible puzzle. (though if i can just find something off the shelf to buy i guess i don't care about the puzzle).
The people doing the crazier builds do a lot of DIY stuff on top of putting off the shelf parts together, like delidding (previous Intel CPUs), combining different coolers' heat sink and fans, 3d-printing ducts and fan adapters and getting custom cables, and possibly even building custom loops with external PSUs etc. But a basic Dan A4 build with Corsair SFX Platinum PSU + mainboard + CPU + Noctua NH-L9 (or Cryorig C7) + RAM + M.2 SSD + 2-slot GPU is pretty easy. There's a lot of effort to be spent on optimization (starts with picking the parts) to get high end components to also run cool and quiet (-ish), though.

If you don't need the Dan A4's minimal size, I'd still go with a slightly bigger case like the Louqe Ghost, Ncase M1 or whatever else exists now with a volume of 10 to 20 liters. That lets you get proper air flow through the case, and use larger CPU coolers (or larger radiators) for higher performance or lower noise.

The SF line's original cables are pretty stiff which can be a pain for cable management in tiny cases but you can buy individually sleeved cables (and the Platinum PSUs come with them and the ATX bracket by default) and other than the cables being a tad long for tiny cases, they're much easier to use and I didn't notice anything wrong with plugs. Fitting the 24-pin power plug into new mainboards has always been a pain in the rear end.

You can absolutely run a "95W" CPU (realistically they all use much more if they're allowed to) no problem in a Dan A4 with minimal tinkering, I ran both a 7700k (delidded with LP53 heatsink + Noctua NF-A9x14 fan) and a Ryzen 7 2700X (stock Noctua NH-L9a-AM4) in mine and the only way to get close to throttling temperatures is by running stress tests. There's no need to downgrade to 65W CPUs if you don't want to. What you do is set a long term power limit in the mainboard's BIOS, eg. to 95W. Both the old-ish AsRock Z270M-ITX/ac and the more modern Gigabyte B450 I Aorus Pro WiFi I tried had this option. The CPU will still reach its boost clocks, just not for as long (and not as many cores at once) but you usually only lose single digit % of performance compared to the same CPU fully unlocked in a larger case with a bigger cooler.

The Black Ridge is an okay cooler but for the maximum performance you'll need to use VLP RAM and a 120mm fan, otherwise it's about on par with the Noctua NH-L9 variants. On most AMD boards it has compatibility issues because the retention mechanism for some insane reason supports old AMD sockets like FM2 so people had to file off parts of the brackets or they would collide with mainboard parts. Also people suggest using it in an intake configuration so it blows on the mainboard/VRM. If you get an AMD CPU you can just use the Noctua NH-L9a-AM4, its heatsink is larger than the Intel variant. The creator of the case also suggests using a fan duct (you can find templates for 3d printers on the internet for most of the common coolers/fans) to reduce noise and improve airflow, he says it dropped temperatures by about 5°C for him. On the NH-L9a-AM4 another option is to use a 120 mm fan (like the Noctua NF-A12x15) with a fan adapter.

The case fan below the PSU is useless in my experience. It's almost entirely blocked off by cables and the PSU and mostly serves as a noise generator. The new mounting spot under the mainboard helps cool the board/RAM/VRM so that could help, but it's a super tight fit.

It's not recommended to use non-Z platforms with Intel CPUs outside of minimum budget builds, because they have fewer PCIe lanes and even if you're not overclocking the CPU you lose the ability to run RAM over 2666 MT/s (which you should because 3000/3200 MT/s is equally cheap and helps with minimum framerates in games).

In your targeted price bracket I would strongly suggest going with AMD though. With a good X470/B450 board you can potentially also get another upgrade in a year vs. Intel's current consumer socket being a dead end. The only challenge is getting a board that already has the BIOS update to support Ryzen 3000 - or finding a way to update it (computer shop, friend with 2000 series CPU, or the AMD upgrade kit where they send you a CPU just to flash the BIOS). AMD makes great CPUs these days and the 3rd generation Ryzen CPUs use less power - the Ryzen 5 3600 is as fast as the 6c/6t parts your Intel builds use, a 3700X would be even faster and have more cores/threads again and it has the same 65W TDP. Together with the MSI B450 I Gaming Plus and Gigabyte B450 I Aorus Pro WiFi the Asus Strix X470-I/B450-I are all decent mini-ITX boards for Ryzen, though the Asus parts are the the only ones of the four to have two M.2 slots.

Also as far as I know you can't override the minimum RPM of the RTX FE cards, they don't have fan stop and can't be made to stop while idling. Nvidia claimed it was a software/firmware issue at some point but I'm pretty sure they have no intention to "fix" this.

The cables of the platinum PSUs are a tad too long but I found them a lot easier to fit than the stiff plastic cables of the non-platinum SF-series PSU I had before. Without an AIO and SATA drives you have plenty of space under the PSU to hide them though.

It really depends on how much you value the size of the case. The Dan A4 is around 7 liters and it's basically the smallest volume that reasonably takes "normal" hardware (SFX PSU, mITX mainboard, full length 2-slot GPU). A Louqe Ghost S1 isn't much larger at 8 liters, with top hats you can get it much bigger though. A Node 202 has size restrictions for GPU and coolers that are closer to a Dan A4, but it's bigger (11 liters) but also much cheaper and uses a "desktop" form factor.

The other "common" SFF cases are much bigger (Ncase M1 is almost 13 liters, almost twice the Dan's volume) which makes a huge difference because many GPUs today are 2.5- or even 3-slot designs (so you can get cooler/quieter ones if your case doesn't have a 2-slot limit), and having room for 120 or 240 mm radiators or 100+ mm tower coolers is a huge game changer compared to the about 50 mm clearance in the Dan A4 or Node 202.

I wonder if the full copper AXP 90 is going to be noticeably better at cooling CPUs in the A4, especially Ryzens since they don't have the option to use the LP53 heatsink (and the Blackridge is bad unless you want to take tools to the retention mechanism and use VLP RAM):

https://smallformfactor.net/forum/threads/thermalright-axp90.11795/

Last weekend I built another A4 based on a Ryzen 3700X with a friend and while the Noctua cooler is fine in general, the Ryzen boost behaviour makes the fan spin up more often than I'd like (my friend is fine with it, he also has a Zotac RTX 2070 Super that sounds like a jet taking off when the fans spin up at launch, I don't know often they do while gaming though). Maybe a more potent heatsink could help (the one of the Noctua NH-L9 is just tiny).

You can technically fit two 2.5" drives (one if you're using the space below the PSU for something like an AIO or unnecessary auxiliary cooler) or more if you want to tape them somewhere, but that just adds more cable routing headaches so I strongly advise against using SATA drives in the DAN A4. My friend who originally wanted to put a 5 TB HDD into his A4 gave up and just got a 2 TB NVMe drive and an external HDD when he looked at some builds.

The Dan A4 can fit three SATA drives, at least theoretically.

Oh right you can fit two below the PSU, even though that would be pretty :suicide:

One drive up front maybe one below the PSU (where everyone wedges a fan for whatever reason) or just tape it in wherever it goes
The fan below the PSU is super pointless, I tried it and the only thing it helps with is making more noise. Without modded cables the space below the PSU is so filled with cables there's just not going to be any airflow. Condolences to people who fit a 545LC/645LT AIO there :v:

I want to try to mount the fan below the mainboard but I doubt that will really help either.

It depends on what kind of components you want to put in your system, what kind of performance you want out of them, and what specific case. What were you looking at?
Yeah this. Some cases are more "small form" than others, sometimes you can fit a small tower cooler that will stay relatively quiet (unless you're trying to run overclocked Ryzen 3950X or i9 9900Ketc. CPUs), in others you can still achieve quiet operation with some 50mm top-down cooler as long as you limit the CPU to some low-TDP model or set strict limits in the BIOS. The same is true for GPUs, a few SFF cases take 2.5 slot models that run fairly quiet, others are limited to smaller cards and a RTX 2080 Ti in two slots is just going to be somewhat noisy, but a RTX 2060 or below might not be.

And watercooling isn't necessarily going to help because if you don't have room for proper air cooling you often don't have room for large radiators and large fans either, so pump noise + small fans spinning fast are still a thing.
