I'm all on board with the Tom's philosophy of bang for the buck. I was all ready to go with an OC'd i5-750 and two ATI 5770s in XFire.
But I need a desktop enclosure and that really limits my cooling options due to clearance issues - and thus my ability to OC.
Got a bit confused with your statement in the original post. Do you really mean "I need a desktop enclosure" or you do mean "I have a desktop enclosure" or PC Case that really limits your cooling option due to clearance issues?
