I see 2 major issues with that build.
First, do not go and spend $1500 on a computer and then use a $20 walmart keyboard. That is retarded. Go buy something decent from logitech; you can get a $25 logitech keyboard from newegg that is lightyears better than the *edited* walmart carries.
Second, do not spend $1500 on a computer and trust your computer to a raidmax power supply. Seriously. Get something from a major brand please: Thermaltake, Antec, Coolermaster, OCZ, etc. Believe me, you will regret it if you don’t.
Other than that it should be a nice computer for you!
