Is there anything I can do to make this build better? My budget maximum is 850. Any of you have any experience with these parts/know that some of them are good/bad anything?

Also, do I need a cooling system like the Corsair H50? <Important, because I don't want my PC to burn out.

 

Thanks for your help!

If you're not overclocking you don't need an aftermarket heatsink.  Also chuck out that Hitachi harddrive, They are made out of shit and semen.

what hard drive do you recommend?

Seagate barracuda or a wd caviar black

thanks, fixed: http://pcpartpicker.com/parts/partlist/

it's a little over 850 though
