Here ya go:
Mobo: ASRock is quickly becoming well known for very very solid products at very low prices. I have one in this rig, and it runs beautifully.

CPU: While this Intel is labeled at a Corei5, it's actually a Corei7 without Hyperthreading. Most modern games don't and won't be using more than 4 cores, so the loss here is minimal. It features a very aggressive Turbo Mode to accelerate games that only use 1-2 cores (the majority of them). For $199, it's unstoppable.

RAM: Cheap, reliable, built to last. GSkill is a purest company, and they know their stuff. I won't touch any other brand with a 10ft pole at this point. GSkill has yet to release a faulty series. I use this exact RAM in my system, and it pops up with its XMP profile instantly, and performs like a champ.

PSU: While Corsair has fallen from grace in a few areas of their memory line, their PSUs have become some of the highest rated in the industry. They are affordable, reliable, and provide more than enough power and features for almost any build.

GPU: XFX moved over to be an ATi partner a while ago, and it seems to have gone well for them. They make good cards at good prices. While they may not have all the bells and whistles others do, you pay 30-50 less per card typically. (Updated to Reference cooler card due to stock issues*)

HDD: Personal preference and opinion here, but I have a thing for Seagate. They have had their issues, but they have fixed them. Seagate is very innovative, and their drives are some of the most reliable as a result. I have never had a Seagate drive die on me, EVER.

Case: This is a new company I've been reading up on. This case has received good reviews on Newegg, and other sites follow suite. AZZA seems to be the Japanese version of Antec, but, with Thermaltake styling (aka better in my opinion) Did I mention they are cheap!?

Optical Drive: Reliable, quick, cheap. LiteON is a pretty easy choice these days.

Total price? $1,046.01 (and this includes shipping!) Mission accomplished.
