Edit: just noticed I had the 16gb of ram in there. I was debating between 12 and 16.
DVD Drive - Good
Case - A bit expensive, I'd settle for something $50-ish
Hard Drive - No. Go get the one that's on sale right now, if it's still on sale. You can get a 1TB for the same price
Wireless Adapter - $30 on Wireless? I'd go with like a $10 USB one and you can swap it out and shit, plus Ethernet is the way to go
Graphics - It's a good mid-level. Don't expect to play Crysis max settings
Power Supply - I like to cheap out of power supplies. You can get one with similar watts for $50. What you're getting is crossfire ready and certified, but you're not even going to do that so what's the point? It just makes it cost more
RAM - Good
Motherboard - Once again your motherboard is too "good" for what you're going to do with it. You could probably save $50-100 with a lower one, 4 RAM slots, etc. Plus, pay attention to the reviews. This one got a 3/5 and you're spending $160 on it
Processor - Don't make the same mistake I did. Just get the best AMD six-core out there. It'll cost less, it'll get outdated less, and it's better. Intel just over-prices all their shit and until their six-cores are affordable, it's not worth it.
Windows 7 - Don't buy it wtf are you doing. Download Windows 7 Ultimate and get a key off someone for $10 or something. You're wasting your money
Cooler - Don't get this one. Get the HC70 for around $40 more. It's a liquid cooling system and you can overclock it higher as far as I know, plus you don't have to worry about it not fitting in your case as long as you have an extra spot for a fan. You can settle for the HC50, that's good too and about the same price as the coolmaster V8
tl;dr: Get an AMD six-core, no Windows 7, different cooler, different case, different power supply, different motherboard. You'll save a few hundred and it'll be better.
