Yea man that power supply is excellent, top quality. The larger the fan typically the LESS noise it will makes, but at the same time pushing more air and giving you more cooling.
I don't think two optical drives are necessary. Just one NEC DVD burner will do. You can just use it to read all your CD's and DVD's as well as burn them.
And the computer will be pretty close to a dream machine. It's going to be a beast, no doubt. It will handle any game at higher settings with no stuttering. So looks sweet overall. And heck, if need be, especially with that nice mobo, if there is ever a need in the future to overclock, you will be able to.
