i waited, and waited, and waited for the mac pro refresh, then they announced this useless ornament and i spent the money on building a MUCH more powerful PC, Hackintoshed it, and now i have the Mac Pro that "Should" have been, Internal, easy to upgrade 2TB SSD Raid boot drive and an 8TB raid with redundancy for local storage, easily, "OFF-The-Shelf" upgradeable high end graphics, and a user replaceable CPU, and drives,
All in one BOX, no messy thunderbolt cables, caddies, external raid enclosures and additional plug sockets to find.
Out the back of my box are three cables, Video, Keyboard and Ethernet (mouse is wireless), i have a workstation that's fit for purpose, and is not a spaghetti mess of cables and extra boxes.
it seems apples approach is "here is a piece of art" its natural state is to be in the middle of rats nest of wires, enjoy (oh and you'll need to buy a new one every three years or less).
