Rate this Build.

I'm looking to spend about 800 USD To Build a New Comp. I've been using a woefully slow Dimension 3000 still using a PCI graphics card. Ive built a few computer's for my friends, but nothing really fancy. Can someone rate this build. Im going for an 800 Base, but will be upgrading the case, and going to SLI before to long.

Current Price is $791 w/ Shipping.

Keyboard and Mouse and Such are taken care of. Will be playing games in 1440X900.

I'm looking to play some newer FPS's like CoD4 and Crysis, but also have a solid FPS playing an MMO like WoW or something.

I'm looking to upgrade this build to keep up with newer games as they come out. (Through SLI, or other such methods.)

My Question is this, How well will this build work.

Spend $11 more and get this RC-690 case. Then you won't need to upgrade the case later.

Thanks for the input dirt. Like I said, I am confident in the assembly aspect, but a little lacking in part awareness. This build is going to allow me room to upgrade later on without a completely new build.
