Good man!
Im doing the same roughly on the 18th of november (pay day!!!).
Except i wont be going through my company... cant justify why id need a computer at work when we already get them.. plus they gotta be explosions safe (work in a petrochemical plant... might blow up if theres sparks or open flames etc...).
The specs im planning on....
Nforce 6 intel motherboard (due in november... meant to outclass the 4/5 series)
Core 2 duo E6700 (gonna overclock it... somebody i know has it OC'd to 3.8 gig)
2 gb DDR2 800 (pricy but worth it)
EVGA 7900 gtx (using the evga step up program i get to change it for a Dx10 card when they launch and i only need to pay the difference in original prices)
Sound blaster x-fi
2 Raptor 150gb 10,000 rpm drives (probly with a 3rd large drive for storage)
Seasonic 650 watt PSU (gonna get quad sli dx10 cards in the future)
unlike youself im having to spend a fair whop of cash...

(£1410 to be exact... plus ill need to get a good cooling system)
EDIT: the computer im using the now was attained via the same way as you got yours.... got 2 years out of it with minimal modding.
