I am selling a used iMac that I purchased from the Apple Store in early 2010. It is the 21,5 inches model with a 3.06 Ghz Core 2 Core processor. I upgraded the RAM memory to 8GB and it has a 500GB hard drive. It is in excellent working condition. It comes with a wireless keyboard and mouse. I will also throw in a sealed copy of Microsoft Office Home & Student Edition. Mac OS X Lion is also installed on it.
