I've got a 20" iMac Core Duo (late 2006) and I'm trying to decide what to do with it. It's suffering from the chronic graphics card issue which has plagued this particular model, but it is out of Apple Care and I'm not sure I want to spend money to fix it. I replaced the machine with a 24" iMac a few months ago, and it's since been sitting in it's original box in the storage closet of my office.
I'm just looking for ideas as what to do with the machine, ideally I'd like to sell it... but I'm not sure it's worth anything in its current state. Suggestions?
