^+1 i agree with everything cmcghee358 says about your build.
You're buying a $200 mobo seems a bit too much for what you've listed.
Why not get a quad core i5 750 it's $10 cheaper.
You can get nice fast G.skills 1600MHz CL7 ram for a good price.
At least buy a ModXtreme psu.
Not a big fan of Thermaltake cases.
I would buy a CM,Antec,or Lian-li.
But cases are a personal choice.
