Apple Mac Pro (Rack, 2019)

The rack-mount version of Apple's Intel Xeon W Mac Pro: the same logic board, 8- to 28-core Xeon W-3200 processor, 12 DDR4 ECC DIMM slots and eight PCIe 3.0 slots with two MPX bays as the tower, in a 5U rack chassis with quick-deployment rails instead of feet or wheels. Aimed at facility installs (broadcast, post, data centre) where the tower's footprint doesn't fit a rack.
