CPU: i7 920 (not overclocked, yet) (thermalright heatsink w/ 1 noctua fan and 1 TR fan)
RAM: 6GB DDR3 1600mhz
GPU: GTX 285 FTW (nvidia ftw, pricey but they outperform ati)
HDD: 3x320GB, 1x1TB, 2x250GB
PSU: 850w enermax
Mobo: EVGA Classified (ridiculously expensive mobo, best i7 mobo available)

On a side note, SLI and crossfire are pointless. Unless you're some 3D modeler or similar, you will NEVER use the full power of all your GPUs combined.
