Look forward to your build log. You come up with interesting designs all of the time. This last case you mentioned gets me into thinking about a watercooled one-off on a smaller budget. SFF is great but when SFF and watercooling meet, it's very awesome.
I wanted to make a kind-of H2O Micro reloaded by watercooling both the CPU and GPU, hence the dual 92 radiator.
Honestly, this is way to complicated in 5L without custom waterblocks... also, the case comes a bit too large, losing the "thin-itx spirit" of the project.
Will start again in smaller form factor, by watercooling the CPU only.
@RoLexus : if you want want, I can put you in contact with the person that designed that load switch. He has all the necessary contacts to build larger quantities.
You 12V LS will be a option, I prefer buyer buy directly from you, I only order in special case. Any way, PM me your contact.
I'm actually seeking for some vendors who can fabricate my PCB design or design/ fabricate follow customer request.
You know, vendors from China, Taiwan, Korea.. are very strong.
If you want some more inspiration take a look at this, here is a fully watercooled build, under 5L. Radiator is narrower, a triple 40mm rad, so that's why it can be that slim. Downsizing the radiator to a 60mm size is a good step, so I'd like to see how you pull it off.
Also, kind of a fan of getting the most out of small power supplies. Are you going to put an internal PSU in that case? It looks like you would be able to fit a 200W Meanwell in the space right beside the graphics card.
