Need help with first build!

[Phyraan]

As the title says I am building my first computer. I want it to be able to run ultra graphics on WoW comfortably with no lag. I would like to keep my budget under $1500 but I will pay what I have to. I do not need a monitor or any peripherals. If anyone could suggest a complete computer build for me that would be very much appreciated! (New parts only, I do not want to use any parts I already have)

You're welcome to change to another case if you like. I just picked one that is likely in the price range you're looking for (there are certainly cheaper ones). I also assumed that there weren't too many other AAA games (i.e. games that take up a lot of space) so the 120gb SSD ought to be enough. If you need more, just get the 240. I also assumed a 1TB HDD, but again you can remove it if you want.
