Edited your build slightly. Changed the case, changed the gfx card to a dif brand, and added an optical drive as you'll need one. The case and gfx card are cheaper, and I had to add a cpu cooler, as if you are going to be over clocking the i5, you'll need one.

Sadly, i do not have a microcenter near me. may i ask why you changed the case?
And, could i get a cheaper motherboard? maybe around ~90$ or is that a bad choice.
Thanks!

If you will not overclock then you DON'T need 3570k cpu (go with 3470) and DON'T need z77 mobo ( go with H77 or B75)

Here. I'll break it down for ya.

If you are going to over clock, keep the 3570k. If you are not, get the non k version, or the 3450 / 3470.
You can get a cheaper motherboard, right now you have one that will give you good oc and crossfire.

This is the new build. http://pcpartpicker.com/p/njLe

If it still pops up for the 3570k at micro center, just go to ncix.com and look for it there. it's $215.99
