Can someone confirm that this is actually a 4u rack mount case, with a cover? From what I'm seeing, it appears to be too small for the cards + power cables and power supplies? (I ordered 1 server PSU and 1 atx PSU, was assuming both would fit.
No, the motherboard is too wide to fit into a standard 19" rackmount case. I'm working on some ideas to fabricate mounts for installing it length-wise.
