There's a used mac pro for sale locally. The ad says it's a quad 2.8 with 2 GB of RAM, an ATI 2600, a 320GB hard drive, and Leopard. So far so good, right? sounds like a non-upgraded single proc Early 2008 Mac Pro. The seller claims in the ad to have bought it in 2006, though. I emailed him asking him if he meant 2008 or 2006, and if the latter, what it really was, and he says he just copied down the info from the invoice, but that he did buy it in 2006. The price is good (but not low enough to send off warning signals), so I'm going to have a look at it - I assume the model number on the case will be the easiest way to tell what it really is - anything else I should pay attention to? I know About This Mac can be easily changed, but is System Profiler (either gui or from the Terminal) be so easily fooled?
