Dell it. At that price range, including software, a monitor and "a dual core processor" (which to me reeks of "I want it because it sounds good" instead of actually knowing what it means and what the difference is and why you'd use it) you'll be hard pressed to get something worth buying instead of saving for longer and getting something at a nicer price/longevity range. And as said before you'll be over fixing it every time it crashes, BSODs, spyware, wife found the porno etc etc because you built it for him. Get a Dell, if only for the bargain price (with monitor and windows) instead of the other reasons.
