Upgraded Build now $1000 - Please Critique

Sorry guys, I know you already helped me, but the game has changed a bit. I decided to get a newegg preferred account and signed up for 12 months no interest, but I have to spend $1000 to qualify for that offer. Or I could do $500 no interest for 6 mos. at newegg then pay cash for any lower priced parts at other retailers.
Well here is what I have so far, this time I came up with my own stuff, so let me know if there is something better out there!

ADDITIONAL COMMENTS: It's a pet peeve when my graphics card overheats and dies so hopefully a case with excellent cooling abilities, i don't care about noise so much

Also, Thank-you in advance for any suggestions and sorry I don't have any real parts preferences, I have researched quite a bit, but the forum debates are overwhelming !!!! lol

GAMES I PLAY OR WOULD LIKE TO PLAY: Empires: Total War, Crysis Warhead, Supreme Commander, Far Cry II, Flight SimulatorX, Rise of Flight, Storm of war: battle of britain, COD4

Please critique this and let me know if I can do better for less. I know people will probably tell me to get the antec 300 Illusion instead of the 1200 but I am just paranoid about cooling when I overclock and may someday use the extra room. I have had bad experiences in the past with non-overclocked heating disasters. I also tried to make it as future proof as possible without huge spending.

How good is the cooling on the haf case obsidian?

The HAF 922 is a mid tower, not a full. The HAF 932 would be comparable to the antec 1200; the Antec 900 or 300 Illusion would be comparable to the HAF 922. All 5 are good cases with good airflow. IMO you should pick between them based on price and aesthetics.

A HAF 922 at $70 is a great price, but if you try to buy it there - its special order so no reliable shipping date and shipping is $23. Some of the cases at newegg get free shipping, which is huge for cases.

$70+$23 =$93 and the case is $110 on newegg http://www.newegg.com/Product/Prod [...] -_-Product
