Help with a $750 gaming pc build with the OS included?

I really want to get into PC gaming, I've only ever played consoles and recently I'start after watching a lot of computer build videos, but no one ever makes one with an OS included into the price.  I want a $full gaming pc build and I want to be able to play skyrim, arma2/3, BF4 when it comes out, Rome:  Total War, games like those.  I would like to be able to play medium-high settings and of possible higher.  Also, and if this isnwant possible for the price that's fine, but I'd love for the case to glow blue, like the antec 300 illusion.  Thank you so much for any help you can offer me


Wow, that's perfect. Thanks!
