Good to hear.
Good luck with the 4th core unlock, let us know how it gets on!
Sounds like a good set-up, though was that the black edition or standard 720 you bought?
Probably wise holding out on the graphics (considering the motherboard has it built in) but should let you assess the case, and what will/won't fit
EDIT: Keep an eye out on the 4870 prices, they have approached the £100 pound mark from the release of the 4770 so you could get a pretty impressive rig put together for peanuts! HEXUS REPORT
