Should i make this $850 build?

Here is the build http://pcpartpicker.com/p/FPYo

 ill probably get Windows some other way but i added it anyway. i might be able to scavange my tb hardrive from my current computer but im not sure if its worth it i dont know what kind it is or the RPM.

I like it sexy, ;) only I'd go with a Caviar Black or Seagate Barracuda instead of a Caviar Blue. Apart from that looks legite to me homie.
