Feedback/advice on my first build

I have been planning my replacement for my old core2duo comp and am just about ready to pull the trigger so I can have it up and running for some of this fall's new games.

I wanted to get some advice and thoughts about the build and see if there is anything that I am overlooking. This will be mostly for gaming, no video editing, some photo editing. I will probably try to oc a little, but since I've never done an oc before, it will be just some minor increases. In the future I will probably add another 570 in sli.

so here goes,

So, any thoughts on the build, whether I will run into issues during the building process, or if there is something component that will be a better fit?

All feedback is welcome.
