I have a 2011 Mac Mini with an upgraded 4GB of RAM.
Used as a home media PC so extremely light use.
Comes with a a 2011 Apple Wireless keyboard and Magic Trackpad connected by a twelve south Magic Wand.
Also comes with a Samsung 3D Blu Ray external USB disc drive.
Currently running OSX Lion 10.4.
Mac is immaculate with the exception of underneath where the removable disc base has surface scratches. I must stress this is the base of the Mac and it has done nothing but sit on a desk. Scratches could not be helped. Unelss you want to sit with the mac upside down looking at the writing underneath however you will never notice.
Cost £750+
Would accept £550
