Probably because the classic mac pro has all but become obsolete with the lack of non 2009 I/OIt will be sad to see you go. Can I ask why you're selling?
I love my mac pros to pieces. but every day I look at my windows computer and wonder why the mac pro couldn't have had minor spec bumps through 2012 with USB 3 and PCIE 3 and Bluetooth 4 ect ect.
I mean come on guys, the sata ports are only gen 2..
