guys... guys... relax they are just hard drives. everything screws up, on either end, anyways back to his build, if you want budget then the e7300 will be fine, and as they've said overclocking moderately is easy, just upping the fsb and multiplier a little bit at a time, now later on your gonna get addicted to it and start learning how to mess with vcore and vdimm but not now.
I bid you good luck and welcome the great computer world
