Needed a sturdy, fast machine for programming/database work, with occasional gaming on the side. I built in Mid-December, but decided to share it.
CPU: I was originally going to get the i5, but the i7 was on sale at 229.99, so I figured why not. I do enough programming to take advantage of hyper threading.
CPU Cooler: This thing is a monster. It weighs a metric ton...I thought it was going to snap my mobo in half. Luckily it didn't (not yet anyway), and it keeps CPU temps nice and low.
Mobo: It does the job. The excellent fan controller and bult-in Wifi were big selling points.
Memory: If you get the Noctua, you have to get low profile Corsair RAM if you go with Corsair or else it won't fit. It didn't recognize the RAM initially, had to go into bios to manually set the timings. I do a lot of database work and use ramdisks, so the more RAM the better.
SSD: Once you go SSD, you don't go back. This blazes through startup and the machine is always lightning-fast. 840 Pro is one of the best, and a significant improvement over 840, which I would not reccommend over the proven 830 series.
Video Card: Handles all my Steam games just fine. FarCry, Hitman, and Sleeping Dogs all came with the card, and all played flawlessly on max settings.
Case: It's a sturdy, no-frills case with sound dampening panels and good cable management. I removed one of the drive racks since I wasn't using it to improve airflow.
PSU: After all the horrible luck with PSU's I've had in the past, I went for overkill with a quality brand. I don't expect any problems. 850W is obviously too much, but I expect to add another GPU to crossfire at some point in the future, and would still like the breathing room.
Extras from old computer:
-2 24" HPw2408h monitors -Win 7 Ultimate -750 GB HDD 7200RPM WD -CD/DVD reader/writer -HP wired keyboard, HP wireless mouse, XBox controller for Windows, basic headphones -Have a 120 mm fan, haven't installed it yet. Will be at the bottom.
Total cost was ~$1290
