1st Build Hardware Help

[The_Cloak]

Hello everyone, I'm a first timer with building a PC, so I thought it would be wise to ask some more experienced peoples' advice before I get started. I have what I believe is most of the necessary parts picked out, so I was hoping some of you could check it out to see if I'm missing something or some of these parts aren't compatible. Hoping for a decent gaming PC, not planning on Crossfire/SLI though. Thanks in advance!

Here's what I have my eyes on:

Case:
-Rosewill Challenger U3

-Apevia ATX-AS680W ?
