The case is pretty crazy in price. While it is most likely a very solid case, you are still paying $190 for a metal box.
The PSU is also $240 and while once again it is probably very good, the price is pretty damn insane. You could drop down to something like this for the two 670's and save a lot of money while still having a quality PSU:http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021
High end builds aren't my thing though, as I'm more experienced with lower costs builds ($500 and below).
