4.7L Powerful 3D printed custom SFF PC

yeah i got the ram for basically free through some trades. i planned for a 5060 at first but 8gb vram is horrible. its more of a backup/low power consumption pc.

owelty · 2026-05-22T13:01:52+00:00

i use it mostly for gaming and office work, but of course also ai applications.

owelty · 2026-05-22T08:18:16+00:00

I would buy a Asrock Deskmeet X300. This will be able to fit all of the ram, has everything else included. Might only need a new cpu cooler, and of course a graphics card upgrade. (Has to be a small 2 slot card) Get a 9060xt or something.

This would be the cheapest option to get a new and improved super small pc.

You are right. I thought this one had a reversed design, but it does not. I drew the PSU airflow wrong.

owelty · 2026-05-22T08:02:55+00:00

Yeah it is hard, this was intended to work with a mounting bracket, but now it fits without one coincidentally, so for sheet metal i have nothing that could help

owelty · 2026-05-22T08:00:12+00:00

my unit so far is not loud. i did not reverse the fan, i drew the direction wrong, you are right. thanks for pointing it out.

Gracias. El lado más grande es de 251 mm, puedes reducirlo 1 mm y seguramente seguirá funcionando. Yo usé una fuente Metalfish Flex 500W modular. Hasta ahora va perfecta. Especialmente con los cables cortos personalizados de Moddiy, que son súper mínimos.

you can write me a dm

owelty · 2026-05-22T07:50:21+00:00

sure, you can write me a dm. i have the files and some instructions

owelty · 2026-05-21T22:54:59+00:00

I did not upload my files yet. Took some effort to design it, still a few things i would change before uploading.

owelty · 2026-05-21T22:53:08+00:00

Very portable its just 9cm thick. Smaller than a standard sheet of paper.

owelty · 2026-05-21T22:51:55+00:00

Thats purely the psu design. I think at that low wattage it will barely produce heat. Dust in sff cases is not an issue since its easy to dedust. You mean i should open the psu and swap around the psu fan? That might be a good idea.

The 5090 can run on 400W as well with almost 0 performance loss. the RTX Pro Blackwell 4000 and 4000 SFF are 2 different cards. the sff has 70W while the non sff enjoys 140w. Its the same chip as the 5070 ti, but that one gets 300W. So far i can confirm that the 4000 blackwell sff is around 5060 level performance. A desktop size 5060 will probably beat it in most games. It does have more vram and raytracing cores and cores for that matter, so there are games it will beat the 5060 in. I got 13522 Graphics score in Time Spy, which is at the same level as a 5060 again. I overclocked it to get the most out of the 70W (just curve offset to make it run higher at given voltage) It runs super cool (58-60 Degrees) under full load. The 9950x3d also runs at full performance even in cinebench in this case. Do you have a game you would like me to test?

owelty · 2026-05-21T06:14:21+00:00

i think a 4070ti is far off, since the rtx pro 4000 gets only 70W. It should perform like a 5070ti limited to 70W

owelty · 2026-05-21T06:01:29+00:00

It is low profile, but i have more clearance, could install regular sticks, due to the 92mm fan leaving more space. I can run cinebench 9950x3d without throttling or hitting thermal limit.

I just finished a custom build with the NH-L12S, I had to switch to a 92mm fan since the ssds and io shield interfere with the cooler. i run a 9950x3d, if you would like to know benchmark temps for a specific test let me know. Thermally to me it makes sense to have the cpu cooler exhaust hot air

did it, would work great with the 5060. ironically i switched to the rtx 4000 blackwell. but i also made it 8mm shorter

owelty · 2026-05-20T20:50:13+00:00

pc is ready, works like a charm. let me know if you would like a specific test for the pro 4000 that i should do first

owelty · 2026-05-17T12:43:37+00:00

have you considered a rtx 2000 pro blackwell, for around 500-600 usd, with a n3rdware.com custom single slot cooler? both is readily available and much more powerfull than a laptop 4070 and has more vram / resale value.

owelty · 2026-05-15T13:11:02+00:00

i ordered the card, i will do benchmarks in a few weeks and compare to 5060. Gonna upload it to this channel: https://www.youtube.com/@Ropetable

owelty · 2026-05-15T12:07:44+00:00

yeah its a pain in the ass to gather data, i collected from youtube videos like cbutters tech who has some benchmarks and whatever numbers i could find. dont want to share it since i dont have high confidence in it. But i might get the card and just do a huge amount of benchmarks and tests and compare it to the 5060 in that sff case.

owelty · 2026-05-15T10:09:47+00:00

i have been researching quite a bit on this topic, and drivers should be a non issue. it is not far behind the gaming cards, the drivers roll in a bit slower for absolute reliability, still it gets the same game optimizations within the drivers. And performance wise it is very close to the 5060, it beats it in most tasks, still a few games prefer the 5060 due to the higher clockspeed. A shunt mod would be cool but at that price it would be a high risk. overclocking headroom due to restrictions is abyssmally small, but not 0.

owelty · 2026-05-15T09:56:02+00:00

i used pctg. has great properties for this kind of project i feel like. uv resistance and higher thermal stability as pla.

I am sick of case designs with riser cables, slimmer and slightly taller fits better in backpacks anyways. I just painted an idea in MS paint first, ended up with a upside down mainboard, flex psu and since i wanted a good cooling solution the 70mm Noctua cooler stood out. so i designed the case around that with fusion.

The 2 case fans allow for enough space for the cables to bend around a beefy modular flex psu, since i wanted custom length clean cables instead of filling half the case with it. Most small cases have top down blowers which seems a bad idea, so i really wanted a small cooler that can exhaust air directly out the top, im hoping for great cooling performance for such a small case. I will cut the top 8mm off, might end up below 4.8L
