Threadripper PRO WRX80 4U
This rackmount system features AMD's Threadripper PRO processor platform with a large, EEB size motherboard. Threadripper PRO is AMD's workstation CPU family, based on the same technology as their EPYC server chips, with up to 64 cores and eight memory channels. That combination is ideal for applications which need both a lot of cores and high memory capacity / bandwidth.
Rackmount cases offer very little in the way of front panel connectivity - just a pair of USB ports - while the motherboard's rear I/O panel provides the bulk of the connectivity (more USB, audio, and networking). But with lots of space in this style of chassis, a wide range of options are supported internally - including one to four video cards, up to 512GB of memory, and multiple solid-state and hard drive configurations. There are also powerful fans to ensure everything stays well cooled, but at the cost of substantial noise levels.
