^ I saw a laptop like that a while back but it could not make it past the BIOS.
My dream system would be a quad opteron mobo with four magny cours CPUs, all clocked at about 4GHz on swiftech apogee xt blocks, with 16x4GB ddr3 1600 MHz sticks, four ef6 2GB HD 5870s on water at 1100/1600, with a GTX 480 on water at 900/1500 for physx, an adaptec 5455 RAID card controlling twelve 1TB SSDs in RAID10, and a mountain mods extended ascension case. As far as psu... I guess the 1600 watt ultra x4 would be enough power, right? I would also have six 30 inch apple monitors, all six running off apple active dp to dvi converters.
Basically the most overkill system that is currently possible.
