$1200 gaming pc

I would like a computer for mostly gaming.  I do not plan to overclock a ton.  I do not have a place for wired internet so i would need a wireless network adapter. The price should include windows 7 too.  I really like fractal design cases (full tower)

I'm on the same budget and there are some really good builds on the post that I have under "build a pc" You should check it out! The thread is Gaming computer $1200 budget
