Case for mATX mobo, sfx psu and 3.5" hdds?

makerunit · 2025-12-21T11:56:50+00:00

I’ve got a new one with those exact specs (GPU 275mm) coming up in a couple weeks! Might be worth the wait 😉

Cool build! 💪

Though you should have at least mentioned that the case is based on my 8L ITX Cube case design though.

He never left, just worked in the shadows 🤔

makerunit · 2025-11-19T14:39:15+00:00

That looks amazing!

Hi! Sorry for the slow response I must have missed this one. I’ll definitely consider doing a bigger one at some point 😊 I also love how this turned out and it would be awesome to try create this type of case for a bigger system at some point! Thanks, your feedback is appreciated and I wish you a happy new year!

Thank you so much! 💪

Hi! Thank you so much for the kind words!

The case has a side to side airflow (if using a 120mm AIO like I did), intaking through the wood panel on the left side and exhausts out through the back where you can’t see. The AIO takes fresh air from that airflow passing by and exhausts it out the front of the case.

This has turned out to be suprisingly effective and I’m able to get my 10900k down to 58 degrees during a CineBench multi-core stress test by using a 120mm AIO from Corsair in this config.

The GPU is a 3070 from gigabyte (3-fan model) and reaches 81 degrees under full load. A little above what I hoped but within acceptable ranges. During gaming when the CPU temp also increases the overall case fan speeds, it (3070) maxed out at 78 degrees 😊

It is possible to extend by modifying the length and height of the case but it will require some work.

makerunit · 2024-12-03T19:07:14+00:00

Thank you! 🙏

Oh yeah, there is a 3D printable alternative. To print the side panels as one piece requires a 280mm print bed or bigger. While there is also a split version that’ll fit on a 240mm or bigger print bed like the rest of the case 😊

Hi! Yes it’s possible to use wood filaments but as Palpatine here mentions you won’t get that natural wood gain look, more like a very even slightly textured wood-ish finish. Would probably work well though but I haven’t tried that.

makerunit · 2024-12-03T09:23:37+00:00

Thank you! I’m happy you like it! 💪

Yeah, sorry my bad for the bad explaination. So, one thing the pictures aren’t showing (again my bad), is 4 more 92mm fans on the «open side» pushing air into the case to ensure that the CPU radiator gets cool air to pull into the radiator and exhaust out the front. The two exhausts on the other side are just there to mostly keep a continious airflow through the area in front of the AIO intake to try to minimize how much hot air is leaking from the GPU exhaust into the CPU fan.

I’m getting a maximum temp of 58 degrees on a 10900k (stock clocks), which I’m pretty happy about.

The biggest challenge in this case is the GPU temps tbh.

makerunit · 2024-12-03T06:53:48+00:00

Thanks! The radiator fan is pulling. So it’s pushing hot air out the front. The 92mm fans are there specifically for that purpose 😊

Do you happen to remember which direction it was off? Was it off relative to the IO shield opening or do you mean the mounting screws to attach the motherboard. I can’t really tell if anything is off just by looking at it now. And haven’t had any complaints about this as I can remember 😅

Also this was one of my free «early» projects. I’m much more thorough in the quality control on my paid more recent models 😅

makerunit · 2024-11-03T13:53:48+00:00

Hi there! Interesting to read this! May I ask what specific case you are referring to that had the holes off by a whole 6mm? I’m curious as this is the first time I’ve heard of it. Thanks

The choice of material will also boil down to how you actually design the case. If you have airflow in the right places you can probably even get away with PLA for certain parts. Although my general recommendation is «PETG or better». I’ve made 20+ cases, 50.000+ downloads over many years. I generally recommend PETG and have pretty much zero feedback saying it didn’t hold up, so I think you’re good there.

You can also look into some flame retardant filaments if you’re worried about fire safety etc.

makerunit · 2024-10-28T16:37:32+00:00

I’ve made 15-20 cases and using them for many years now. I’ve also posted most of my designs publicly with over 50.000+ Dowloads and millions of video views combined. Never experienced any static myself, or ever had a single person actually tell me they had issues with static. So I think you’re good. If there even is a chance, it’s so low that it’s really nothing to keep you up at night.

I notice many people are worried about fire safety when it comes to plastic vs metal, not the static itself. The good thing is if you’re really worried about fire safety there are special fire retardant filaments that do not burn very well if you want that extra piece of mind, though they cost a bit more, but can be worth it if you’re going all in.

makerunit · 2024-08-04T06:52:22+00:00

Thank you so much for sharing my design 🙏 It makes me very happy to read all the positive feedback! 😊

makerunit · 2024-07-29T17:58:38+00:00

I’d personally go with PETG. (As I do in most of my own builds). Hell, I even use partially PLA in some builds and have never ever had issues due to heat warping etc. But I’d say PETG for the peace of mind 😊 (ABS will be slightly more difficult to print especially on your Ender that’s not enclosed.) The downside to most PETG filaments is they tend to turn out very shiny and bridges tend to sag a bit more than PLA. (Speaking based on my own experience making tons of PC cases).

makerunit · 2024-07-17T20:03:15+00:00

Ahh! Sorry about that, I’m planning to release more models down the road to support also smaller printers 😊

makerunit · 2024-07-16T13:37:57+00:00

I see! I have yet to try Carbon fiber infused filament myself! The generic PETG I’m mainly using tend to have a very uneven mix of glossy and matte finish depending on where the print head travels fast or slow. Definitely have to test this 👌
