I don't know if it's been mentioned, but a cool idea would be to have a normal tower, and you could join two of them side-by-side with the side panel facing the other case removed to make a cube. make a few w/c features and you could use one of them for your water, and the other one for hardware. And for the more xtreme guys, you could start joining 3-4 of them. Heck, make it so you could stack the on top of each other also, and some guys would start playing lego with those cases.
