First custom PC! Runs all my games awesomely, check comments for details. I would buy different RAM; underclocked itself to ~1333 because of voltage. If you don't need the Pro version of the 840, get the 830. Also, the cd/dvd clashes with the front of the case, so I use an old external cd/dvd. Almost everything was on sale when I got it. ~850 w/o rebates.
Achieved 4.2GHz OC stable on the CPU, maxing at about 32c on full load w/room at ~62f.
