Recently, we listed 5 differences between workstations and a regular PC, and with regard to the Socket 1151 platform, all these differences are not relevant, so you can not read the article on the link, but rather look at our review of the server motherboard E3C242D4U2-2T from the company ASRock Rack, created for budget servers. Almost all of the same unique Socket 1151 processor Coffee Lake-S allows in all seriousness on the same platform to build as a 2-core Pentium Gold terminals on Linux with virtually no load, but with ECC memory (for example, for the operator of X-Ray scanner or other medical equipment with a high level EMI Environment), and 8-core, universal machines based on Xeon, which it is possible to work with graphics, and scientific research.
Both in the first and in the second case, you have something that is sold under the loud name “workstation”, more expensive than the usual “automated workplace”, but on the same hardware as in desktop PCs. In addition to ECC memory and motherboard. With memory, everything is clear, but there are not so many budget motherboards for workstations, and even the MicroATX format. ASRock Rack C 246 MWS is one of them.
