First Build, Feedback Wanted!

This is my very FIRST build, so I apologize in advance if I got something that's not compatible or looks stupid to some of you professionals out here  

I scavenged the internet the last few hours choosing parts I felt were good, yet affordable to remain within my budget. I'm ONLY building the tower. Only thing I'm really missing is a good GPU. I want something mid-high end for let's say <$120? If that's reasonable. Also if people could give me feedback on my parts list or recommendations on swapping some stuff out. I'm really hoping there's a deal on the i5 2500k soon before I start pulling the trigger.

I DO have a Fry's near me, NO Microcenter, if that helps any, but all of the parts I've chosen here are all from Newegg.

4. Will you be overclocking?: Possibly in the future.

BEFORE adding a video card my total is $613, so I might have to adjust my budget a little or hope for some sale with a mobo or i5 2500k.

Thanks for looking!
