First, dont bother with liquid cooling. It's a waste for the 965, which runs damn cool.
Go with the HAF 922, its cheaper and is a great, roomy case. Fits any reasonable HSF (get the Cooler Master Hyper 212 Plus). Also, go with the 965, what's another 20 bucks? G. Skill is excellent RAM, and works well with AMD builds. I also recommend Mushkin. ASUS monitors are good bang for the buck, but dont expect perfection. For the mobo, the ASUs Crosshair III is phenomenal. I wish I would have done more research that way when I bought my 790X. You can defintitely fit a 5870 into that budget, and crossfire a year from now and still play anything at 1920. ANYTHING. Well thats all I got. Good luck!
