Bought this Mac Pro Late 2013 for a specific purpose - and this machine fits the bill. Back Market sent me a machine in excellent condition. The only marks on the outside were some kind of smudges on the fan in the top. The cylinder itself was pristine. Opening up the box, the machine was dust free. Back Market even through in a wired keyboard and mouse. Always good to have a usb keyboard / mouse set when tinkering with a machine. The machine itself is fast and reliable. The reason I wanted this model is the support for three monitors... two Thunderbolt 2 (with a miniDP to a modern DP connection) and one HDMI. I have an Ultrawide QHD on one Thunderbolt Bus, plans for a 4K 16:9 on the other and the HDMI into a TV at lower Hz refresh. A++ To Back Market for the buying experience and A+ to price on these making these old Macs now perfect for a special projects machines.
