Actually, if I were you, I'd probably just buy the all new Xbox 360 version that came out, it's $299 without any games, BUT it has a 250Gb hard drive AND it comes with BUILT IN WI-FI which will save you $99 right there AND the best part about it is that with this version, it's got a nice sleek design with NEW vent/cooling system that's supposedly whisper quiet and much better than the old, so you shouldn't have to worry about the 3 rings of death

It's also kinect ready, which I'm sure everyone is gonna want when it comes out at the end of the year.
