Well, existing PC has died, what better excuse needed for an upgrade eh? 
So I'll be ordering to the following spec
Intel Core i7 950 3.06GHz
Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard
Corsair XMS3 6GB (3x2GB) DDR3 12800C9 1600MHz Triple Channel
Western Digital Caviar Black 1TB SATA 6Gb/s 64MB Cache - OEM (WD1002FAEX)
I already have the following
GTX8800 GFX Card
2x WD Raptors
Fitted into a Butterfly V2 Case
This time round I'd like to watercool this setup, what would you recommend?
I'm allowing a budget of £350 for cooling if need be
Thanks!
Rob
