I have an old Silverstone chassis with the NT-06 cooler and the PSU above the motherboard providing CPU cooling, no separate CPU fan needed. But the NT-06 is quite high, the Prolimatech Samuel is 45mm and the Thermalright AXP-100 is 44mm.
So here's my thought: an ATX PSU is only 140x150, slightly smaller footprint than the ITX motherboard. So that's the chassis would look like: motherboard, heatsink touching the ATX PSU and then space next to them for an ITX gaming card, the height is right, those cards are 135mm high, an ATX PSU is 86mm high so a 45mm heatsink would fit. It would certainly be packed to the gills, once assembled there's no empty space that's for sure.
So the case interiors are about 170mm along the PCIe slot axis, the height is again roughly 170mm perhaps a little less, and across you need 170+40 for the dual slot card=210mm. So the outer dimensions would be about 190x190x230 -- about 8 litres with an ATX PSU. Is this a very crazy idea?
