A couple changes :)

First, you can get a better case with a similar quality PSU for less... the PSU won't look as pretty but it's solid:

Are you overclocking? I see no cooler. If not, there is no reason for 1066 RAM. Lets see if you can save any there.

You may have saved enough to step up to a 4870?
