This Xbox has serveral modifications done to it. There is 2 piece's of plexiglass to see the inside. The disk tray has been hollowed out so you can disk spinning in the xbox. It also has 2 led strips that change color on a remote control. The front led has been changed to blue rather that green and the HDD has been hollowed out so you can see the inside of that also. I am very pleased with the outcome of this project.
