I have for sale a Xbox 360 Elite, complete with 120GB hard drive.
The console is in great condition, never had any problems, it has never suffered from RROD and has never been opened/modded.
It will come in its original box along with Power Supply, 120GB HDD, Black controller (brand new), headset (brand new) and composite cable.
Manufacture date for the console is 2009-08-16.
Any questions feel free to ask away.
