Need someone to build computer for me

[Gboogie25]

So I'm building a computer. I want to use it for some serious gaming. I already have the graphics card I need. I was wondering if you guys can build something for me around the $500 range.

I already have the Nvidia Geforce GTX 560. Thanks. I also have a windows 7 copy.
