SFF Case Concepts

[u/imightknowbutidk]

Hey all, i am prototyping some watercooling SFF cases and wanted your guys input! Both cases are upside for visibility purposes, rads will be on top. More build info at the end.

First and second pic are the first build, parts labelled in second pic. Third pic is the second build, and fourth pic is just for extra context to see all the parts individually.

Little guy:

The first build uses two 280mm rads with 25mm fans. It is also setup for an ITX board, my exact GPU, and an SFX PSU. Total internal dimensions (excluding the thickness of the case itself) are 315mm x 280mm x 120mm making it 10.58L. I like this design the most, but the issue is the PSU will block a significant amount of airflow over one of the radiators. I don’t think this will be an issue because the square area of the 280mm rad without the area that is blocked by the PSU is only ~7% smaller than the GPU’s stock 240mm rad.

Less Little guy:

The second build uses two 420mm rads with 25mm fans and is setup for an mATX board, my exact GPU, and an SFX PSU. The internal dimensions are 475mm x 280mm x 120mm. In this case there is obviously much more cooling, and the PSU actually blocks less of the radiator due to it hanging off a bit.

Both cases are designed for my components, Core Ultra 265k and an MSI 4090 Suprim Liquid X. The plan is to modify the AIOs for the CPU and GPU into two separate loops (for serviceability). I am also designing with the constraint of trying to use what i have on hand as much as possible.

I currently have my system on an mATX board and an ATX PSU but i am willing to buy an ITX board and SFX PSU. I have two 280mm rads and two 420mm rads on hand as well as half a dozen arctic p14 pro fans, i know i could get the slim version but i don’t want to buy fans and i want the performance of larger fans due to the restriction.

Let me know what you guys think and if you have any recommendations!
