I have for sale an Xbox 360 Premium system, in as-new condition, complete with all accessories and boxed.
It has had its firmware changed to Xtreme firmware so that it can play backup games (i.e. it has been modded, or chipped, or whatever you want to call it). It has the latest version of firmware - iXtreme 1.4, and has NOT been banned from Xbox Live.
The accessories that come with it are:
1x 20gb hard drive
1x Wireless controller
1x Power supply
1x Component video cable
1x Ethernet cable
£215 includes delivery by DHL couriers on a 48 hour service. I have excellent eBay feedback if you'd like to check that out before you buy.
