PSU - Not sure...don't want to go too expensive, definitely don't want to go too cheap and fry everything with bad luck
Monitor - As I stated above I can use the one I currently have until I get a bit more money saved up again, but if anyone happens to know of a decent ~26" HDLCD feel free.
Posting this mostly to get everyone's opinions on the entire rig as well as PSU suggestions. Hopefully I didn't forget anything. If anyone has suggestions to cut price without sacrificing much performance, I'm very open to suggestions.
HDD: You'll get faster discs if you use the Samsung Spinpoint F3 or Seagate 7200.12 (500 GB or 1 TB models only).
GPU: Agree with rammar. I'd try to get an HD 5850.
PSU: Also look at OCZ, Antec Earthwatts, SeaSonic, FSP, PC Power & Cooling, and Silverstone. All of these are good quality, and fairly efficient.
Another choice I'd like to present. You should consider using an AMD build (specifically X4 955 and Gigabyte GA-790XTD-UD4 for about $304). This would allow you to get at least the HD 5870 as the GPU, which makes it a much better gaming computer. Everything else would be the same.
Thanks for the heads up on that G.Skill ram, MadAdmiral, looks like good stuff. I'll take a look at those HDs too. Those 500GB Seagates would save me about $50 and I'd still have 1TB in RAID 0. I think I would rather stick with Intel though.
