I'm not sure how their policies and customer service are, but the computer I built from parts from Newegg for $850, cost ~$1300 from there.
EDIT: Just did it again. For case and hardware, monitor, peripherals, and OS, it's $1250, and $125 for ground shipping. So $1375, I wasn't far off.
Newegg it is. This is what Tig Ol Bitties recommended:
Raise budget to $900 and you can get a SandyBridge setup including all the stuff you need. At this point, it is the best performing platform at least until AMD's Bulldozer chips release some time in August-Sept. Shouldn't be getting a Phenom II chip at this point with Bulldozer around the corner. If you want to buy in July, get Sandybridge. If you don't want Intel, then wait til Bulldozer drops. I guarantee you won't regret getting an Intel Core i5 2500K, but don't bother with the Phenom II chip.

At most, this will be about $905 before tax/ship. Hopefully, newegg doesn't charge your state tax. These deals aren't going to last long and there is no guarantee that there will be better deals in the coming weeks. May want to jump on it soon.
If you plan on OCing, which is pretty much what the 2500K is meant for, you need a better CPU cooler as the stock one is only good for stock speeds. This is the best budget cooler in the market: http://www.amazon.com/Cooler-Master-Hyper-Sleeve-RR-B10-212P-G1/dp/B002G1YPH0/ref=sr_1_1?ie=UTF8&s=electronics&qid=1308035272&sr=8-1

Can anyone review this for me and give me a second opinion on it. Probably the build I will go for. Everything just kinda... clicks together in the case, right? (or screws in)
