I hate to ask such a basic question here, but does anyone know a reliable source from which I can purchase a Horizontal computer case? Pic related, an old-school "put the monitor on top of this thing" case, preferably in an ATX format with plenty of internal space? I'm limited on available space and want to build a new computer and I'm tired of upright cases.

Background: I'm trying to build a gaming rig (so slim/low-profile cases are out, I need to be able to fit at least four sticks of RAM and a very large graphics card in there). I have unlimited vertical space, but because I'm 6'8" and live in a small apartment, my horizontal space is limited. I need something I can set on TOP of the desk, or on a shelf above the desk, and not have to constantly knock my knees against.
