Apple Mac Pro 4,1 and 5,1 - Dual CPU Upgrade and NVMe

In this video, I will upgrade the CPUs and install a NVMe drive in an Apple Mac Pro 4,1, also knows as the early 2019 model.
The CPUs will be upgraded to two Xeon X5675 and for the NVMe drive, I will use a Samsung 970 EVO+ and a PCIe NVMe adapter.
The process also involves converting the firmare to 5,1 and upgrading it to the latest version: 144.0.0.0 and off course I will benchmark the machine before and after the upgrades.
