The MASTERPIECE V1200 from Mouse Computer is definitely NOT your average PC. Featuring a Core i7 975 Extreme Edition (3.33GHz), three GeForce GTX 285 with 1GB of VRAM each and 12GB of RAM, the MASTERPIECE V1200 is a real monster!
Sold with Vista Ultimate 64, Mouse Computer also proposes a primary SSD of 80GB plus a 1TB secondary HDD and a Blu-ray/DVD burner for a price around 439,950 Yen (€3191).
Definitely not my kind of PC, but I would love to try out this kind of beast one day.
