Budget Gaming Computer

I've been thinking about building my own gaming computer and I want it to be cheap but also perform well and be decent quality parts. I've found a combination that seems to be good but could I get cheaper with still good quality, good performance, and without using integrated graphics?

This build will give you slightly higher performance, and contains higher higher quality parts.

The motherboard has USB 3 but the case doesn't. Will it still work?

My budget is up to $500 (w/out Windows)

Live in Indiana

I have a couple mice (mouses?), but I can get a cheap keyboard at my local Best Buy

Mainly gaming, browsing, and watching Youtube videos

No overclocking

No water cooling

I can get Win 7 and my local best buy

I would like to play games on high settings

I would like to play at 720p or 1080p

Games I will be playing are Gmod, Minecraft (like to hover around 100fps+ on high settings), FPS games, mostly Steam games
