Liquid-Cooled Computer Desk
You have to admit that this is a sexy beast. Popular Mechanics actually constructed this water-cooled mod in May 2009, which features a half-gallon of glycol flowing through 15 feet of Tygon tubing.
On a hardware level, the PC has a XFX nForce 790i Ultra motherboard, 4 GB of Kingston HyperX DDR3 RAM, a 3.0 GHz Intel Core 2 Quad processor, and a Palit GeForce GTX 280 graphics card cooled by Danger Den's Tieton water block. There's a good bet that this PC-in-a-desk could play Crysis and look good doing it, too.
