Xbox 360 slim with RGH3 and internal 4TB, 3.5 hard drive (disc tray replacement) which means the disc tray has been removed and replaced with the 4TB HDD loaded with 3.8TB of 360 games (almost every 360 game available).
Do not go online with it unless you pay for a stealth server (Google it)
It's a fantastic system and I love it, but it just doesn't get the love it deserves anymore as I don't have the time to play. Comes with a power lead and wired controller.
