nice solid build man.

I like this evga power supply though. To me it hits the sweet spot for features and power.

I also like this case better.. and it has front USB 3.0.

Here is another case that is a good deal and has good build quality

 If you can wait a little, GTX 770 4gb should be out soon.. and there are a couple models floating around.. they are worth checking out. They should retail around $450.
