Any suggestions on this build please?

I am looking to do my first build and these are the specs that i have come up with. I believe everything is compatible and at price point before mail in rebates. I will be using this system to SLI gtx 560's for gaming, some video rendering/editing, overclocking, multitasking. Any advice or suggestions before I go to purchase?
