I'd do some more research before commiting. I found a lot of that stuff over priced or a little missed matched, like th motherbaord and case set up they recomend is kind of rediculous.
Seems awefully expensive, especially considering they aren't even building it for you. The 7870 is kind of overpriced. you can get that for at least fifty bucks cheaper by looking around on tigerdirect.com or newegg.com just by adjusting your filter settings.

You are buying a micro atx motherbaord with a full sized ATX case. It's like buying a mansion for a midget. Try this cooler master haf v12. The cooling is great, I loved this case. Very high quality, very easy to work with. Has rolled steel and all that, so you won't cut yourself. Oh, and it's almost half the cost.
