Small PC cases compatible with ATX power supplies

[Lucas Ayde]

I've got a spare GPU, CPU, SSDs and PSU which is most of what's needed to build a new PC and I want to make one for my living room, somewhat like a Steam Machine.

Obviously though I want it to be as unobtrusive as possible so does anyone have any recommendations for a small case that would fit a regular ATX PSU as well as a decent small AM4 socket motherboard to put in it?

Other than buying a commercial case, I've also considered 3D printing one and there are a few that look interesting - does anyone have any experience of that?

The rationale is I want to reuse all my spare parts and the PSU is actually pretty decent but ATX is bulky for a really small case so that will make finding a compact one tricky.
Expensive memory is a bummer but I'm just looking to go with 4x second hand 8GB DDR4 modules which I think should be reasonably affordable as they are typically what gets discarded when people go for 32 or 64GB upgrades.

I have a Lian Li A3 mATX which supports a full ATX PSU (I have an SFX one in mine though).

The Jonsbo D32 Pro also supports an ATX PSU, but has GPU size limitations - https://www.jonsbo.com/en/products/D32PROBlack.htm...

I have a jonsbo d31 with atx, but good modular cables etc advised.

Also not sure if Streacom Da2 might take atx but getting crammed.

I’d get an sf750.

I have a da2 (black) with all the extras and an sf750 in storage, can’t find decent use for it.
I went to Jonsbo d31 but now also to full tower again. Shove it under desk where you can’t see or hear it

I bought a standard ATX sized tower for my media PC. I wasn't too fussed over the size as it matches the furniture and covers the unsightly plug sockets and cables on the wall behind it.

The DA2 will take a ATX power supply but you'll need a ITX motherboard

[Mr Whippy]

Yeah the DA2 is itx only.

Itx is cool and interesting but imo I wouldn’t bother unless you really love looking at your case and admiring its size, or taking it places a lot.

It’s just all downsides on cost, upgradability, flexibility, faff factor, reusability of parts.


I’d just get a great looking atx case on show, or a quiet one hidden away, and go from there. ATX makes life many times easier.

I would be a bit more balanced

Yes its expensive at €200 but its all aluminium
Building it is easy unless you try and fit a big GPU
A good choice for something on your desk versus on the floor

The Cooler Master QUBE 500 Flatpack is kind of interesting looking and compact. I don't think cooling is very good but you could pull out the dust filters if that is an issue. There is also the newer QUBE 540. Both support ATX motherboards but check PSU and GPU lengths and be aware these are not as easy to build in as a full size case.
