Hi there,
Got an iMac 27" Mid 2011 to sell. The specs:
2.7GHz Quad-Core Intel Core i5
4GB 1333MHz DDR3 memory
1TB hard drive
AMD Radeon HD 6770M 512MB GDDR5
Out of warranty but condition very good and well kept.

Comes with Apple Wireless Keyboard that's working fine.
Apple Magic Mouse not working, something wrong with sensor.

Look forward to your PM quote. Thanks!
