This is a beautiful macpro desktop. It is 4,1 firmware upgraded to 5,1 with 48G of RAM, 12-Cores, 256G SSD, and 750G original Apple HD. The latest supported firmware was installed. It has a fresh copy of Monterey 12.7.4 running with OCLP (Open Core Legacy Patcher). Runs great. 1G LAN and WIFI working. For Apple fans, this would make a great addition to your collection. Super clean. I installed the CPUs myself and has fresh thermal paste. The all aluminum case makes this very heavy.  Shipping weight is around 55 lbs.
