So I'm looking to build a gaming desktop on a $400 budget

[RoughNTumble]

I've never built a computer before, and I was hoping maybe you guys would have some useful tips or could point me in the right direction.

I want to get the best bang for my buck.

If you are going to build one from scratch, try Newegg for your parts. For $400 you aren't gonna get very much, though.

Here are some entry level specs, though.
