Stumbled upon this on cl the other day and decided wth, I'll shoot them an offer. Lo and behold, the next day I get an email saying its mine if i want it. 20" apple cinema display. Have always wanted one of these and am super psyched to own one. I have an mid 09 MB and want to hook it up. I ordered one and with prime, it got to me quite fast, but it was not right. What kind of cable adapter do I need?
