2013 Mac Pro - 12 core 2.7GHz - Dual D500 - 64GB mem - 1TB SSD - A1481 MacPro6,1

Description

Here is an upgraded 2013 Mac Pro with a 12 core 2.7GHz CPU, dual D500 3GB GPUs, 64GB memory, and an OEM Apple 1TB SSD. There are no cosmetic or functional issues--I performed the Apple Hardware test and it came back with no issues. The Mac Pro comes with box, power cord, extra OEM Apple 512GB SSD, and an extra 6 Core 3.5GHz Xeon CPU. Yes, there is an extra CPU and SSD included. These were the original components which I upgraded. Now they represent nice backups if the installed components ever happen to fail. The computer has been wiped and the latest version of Big Sur is installed.
This computer has lots of horsepower and is Big Sur compatible. It represents a great value. This is especially true when considering recent jump in computer prices.
