The box arrived at the end of the day yesterday. So far this morning I’ve only unboxed it and gone over things physically. The case has some minor marring on the top and low on the sides - typical for being set under a desk with things sat on top of it and running into the sides with shoes or a vacuum. Other than that, it is physically clean and in good shape.
Going through the internals (it is a Mac Pro), the only thing out of order I’ve found is that I’m missing three hard drive tray fasteners - the ones to attach the drive to the tray.
My next step is powering it up and running it through the TechToolPro tests to see if that turns up any abnormalities.
