I bought - don't laugh - one of the new Gateway (go to gateway.com) - gaming PCs. It was 1.2k, but the rig as they had it configured was actually $200 less expensive than it would have run me to built it myself. It's very quiet, works *beautifully* (as in, I have had all 5 characters moseying around Dalaran during prime time with very little slow-down.
Have had it now for a bit over a month and it's been the best pre-built machine I've ever had!
