A friend of mine borrowed money and gave his mac pro for collateral. Months passed and still no money has been payed to me. However, now I need money to pay bills after being layed off. I told him about it and he told me I can sell it because he has no use for it anymore. I'm new to macs, so please help me out in pricing this mac pro. Is about ~$800 a good price for a mac pro with the specs below? Mac OS X 10.9 Mavericks Specs: Used: 2009/2010 Mac Pro 4,1 -> 5,1 cpu w3690 6 core 8800 GT 250 gb velociraptor DDR3 Ram 16gb If not, what should be the going price for this? I'm from Louisiana. Thanks for your help.
