I've seen the back of this thing - the bottom section can actually take a 16-node blade server (8U). That's 32 processors x 8C/16T sharing 8TB RAM plus 192TB of storage!!!
Wanna fill the upstairs section? Eight GTX690's would get lost in there, along with a pair of dual Xeon boards, four power supplies and another five 480 radiators in push/pull.
