I would start with the $1000 build on the first page. No one knows how Battlefield 3 or Rage will run on current hardware, but a GTX 580 would probably stand a better chance than the GTX 570 in the $1000 build, so I'd make that upgrade (+$200). Other than that, I'd add an SSD for games and the OS (Intel 320's or Intel 510's come highly recommended it seems) (+$150-$200) to go with the HDD for storage. Beyond that, you've got to ask a few questions: The first, will you ever SLI? If not, you could sub out the 750w corsair model in that build, for a cheaper 650w model. If so, you'll need something more along the lines of an 850-1000w PSU (Corsair and Seasonic are my picks for brands). If you want to save money, you could do without the SSD.
Other than that, just pick a case from the list, and you should be good to go. Pick one of the quiet ones for non-SLI, or one of the others (like the HAF 922) for SLI, to take advantage of the additional cooling. Be sure to show us a list of your final parts before you buy, so we can go over them.
, and installing windows 7 atm. However, I didn't create a partition. (I have a 1tb hdd)
