Hi everyone, I found this iMac on craig's list - the seller doesn't know the specs but sent me these pictures. I think it's an imac dv but can't be sure. Questions: 1. What do you guys think this is? 2. What are the likely specs on it? 3. How much is it worth? 4. Can I put OS X on this baby (not leopard, but some other lower form of cat?) He said he paid $200 for it but is looking to get rid of it because he is not using it and will sell it to me for $100. Is it worth it?
