Hey everyone,
So I decided to sell my iMac and so far I've received some offers.
Specs:
-i3 3,06 ghz
-12gb ram
-500gb Hd (7200 rpm)
-ati radeon
Buying price: 1080 (edu price) + 50 (ram) = 1130
Offer: 760
Thoughts?

As a starting point, you can check Mac2Sell, eBay (including completed sales), or Amazon for prices of similar models, to get an idea of what you may be able to charge. Then adjust your price to account for condition, configuration, remaining AppleCare coverage (if any), etc.
