Someone on craigslist wants my 4,1 mac pro 12 gb 750gb samsung evo and 2tb hd in exchange for thunderbolt display. Is this worth it? I was trying to sell my mp for cash...but this guy says that thunderbolt display have better resell. Is this worthy trade? or would it better if I took 2tb hd out from it. If i get this thunderbolt display..would i be able to sell it faster on CL?
