grabcad

A huge thanks to colleagues who provided models of computer components!ATwentyXIdea and sketch and 3D model creation partnership of Karoly Negyesi(La Purd Ltd, Canada)SSI CEB and similar sized E-ATX motherboards like the Asus Rampage V. (SSI EEB definitely does not fit.)1. 120mm rear fan for exhaust.2. A top 140mm slim fan like the Prolimatech Ultra Sleek Vortex 14 also exhaust.3. 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.)4. SFX / SFX-L PSU. Intake from the front, exhaust to the top (or shown variant to the left).5. Every video card there is, 12" and more.6. Two 120/140mm side fans, intake.7. One 3.5" disk or two 2.5" disks on the front. The 3.5" disk only allows for 11.5" graphics cards.8. The bottom fits two 140mm slim fans for intake OR one fan and two 2.5" disks OR four 2.5" disks.9. All this in 178*350*320 which makes it a small form factor case just a hair below 20L.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. lesshttps://hardforum.com/threads/atwentyx-e-atx-under-20l.1928430/
