- SSI CEB and similar sized E-ATX motherboards like the Asus Rampage V. (SSI EEB definitely does not fit.)
- 120mm rear fan for exhaust.
- A top 140mm slim fan like the Prolimatech Ultra Sleek Vortex 14 also exhaust.
- Some 120mm tower coolers, most importantly the Scythe Fuma "simply the most amazing air cooled heat sink I have ever tested". (But also the Cryorig H7 and the Thermalright TRUE Spirit 120M BW Rev.A. In other words, max 150mm high.)
- SFX / SFX-L PSU. Intake from the front, exhaust to the top (there will be a grille, missing from the render).
- Every video card there is, 12" and more.
- Two 120/140mm side fans, intake.
- One 3.5" disk or two 2.5" disks on the front. The 3.5" disk only allows for 11.5" graphics cards.
- The bottom fits two 140mm slim fans for intake OR one fan and two 2.5" disks OR four 2.5" disks.
While there are/were some smaller ATX cases (the GTR GT3-BH ten years ago was 13.6L) they tend to use risers and small fans. And I am unaware of any other E-ATX case in the small form factor space.
We will use the same AC cable as the nCase M1 and will run inside the case along the top, having the C14 connector above the 120mm fan, there's enough space. SFX PSU will connect inside the case. For SFX-L, the same cable will exit the case to the top and connect outside. Very little will be visible of the cable even for SFX-L. This way both SFX and SFX-L are at the same height, their bottom can be supported by a small lip. SFX will be screwed to the front using two L pieces, SFX-L will be directly screwed to the top with the grille removed.
What do you think? If there is interest I would create a prototype crowdfunding campaign and then a normal production crowdfunding campaign.
Ps. With feet and protrusions the case is 178*380*330.
Ps2. For short video cards, we could add a "pile" of 2.5" disks between the video cards and the front. 8 at least but perhaps 10 even. This is not yet designed, it's just an idea in my head. Or we could use the existing fan frame for a few. This will be explored in the future.
Ps3. While the Rampage series should fit, it's very likely only a real prototype can show us whether the ASUS Z10PA-D8 fits, the likely cooler at least for the front CPU socket is the Thermalright 120M. We know the D16 series doesn't fit as those are SSI EEB.
