I've tested this system out and it works just fine. The MW3 noises work when turning on the system. I've formatted the hard drive after tested. Comes with a Black Controller. No games included, just showing that it works. I've blown the system out with an air compressor. Check out the video of it working below.
Comes with:
Black Official Microsoft wireless controller
Official Component 360 AV Cables
Official Microsoft Power Box and Power Cable
320 GB Hard Drive
Xbox 360 Console, MW3
