iMac 27-inch, 2.8 Quad Core i7, 8GB Ram, 1Tb HD ?

Well loved mint condition iMac with fast 2.8 quad core (8 thread) i7 processor. 8GB Ram, 1Tb Hard Disc, Ati Radeon HD 4850 512mb, Osx Lion. Comes boxed with Apple wireless keyboard and Magic Mouse. Reluctant to sell but I have to go all portable! Will come reformatted with a fresh version of Lion ready to use. Any questions please do not hesitate to get in touch.
