Alright guys, Thanks for any/all of your help it is very much appreciated!

That would be a nice gaming rig.. Very similar to my own! I would recommend upgrading to a 4GB (2x2GB) RAM kit and getting a 7200RPM hard drive. 5900 just isn't fast enough.

A Realtek high definition audio is a built-in audio chipset on some motherboards. I don't know if they make discrete sound cards at all. The motherboard you picked out has onboard audio, like the vast majority of motherboards these days. If you want a nice discrete sound card there are some options out there.

if you can spare a lil extra cash try this case its got nice fans in it and its only like 5 bucks more than the one you picked http://www.newegg.com/Product/Product.aspx?Item=N82E16811147144
