OEM motherboards are referred to as custom-built boards, similar to how gaming boards are named. For a Z420 workstation, they might be called professional-grade or high-performance motherboards.
They typically rely on standard motherboards from manufacturers like Asus, MSI, Gigabyte, etc., produced by companies such as Origin, Cyberpower, or XoticPC. For Dell or HP systems, the boards are usually custom OEM products developed in-house and not sold through regular retail channels.
Good motherboards are simply good motherboards. Poor ones get labeled as crap motherboards. It's possible for both to include "gaming" in their names, but that doesn't indicate quality. OEM motherboards are referred to as such.
they might receive a name. HP once assigned location names. My parents' old computer featured an Eureka3 board.
If you own a home PC from HP, visit their support site and check the desktop model. There, they usually keep all the relevant information, including the motherboard model and manufacturer. On some of my old HP desktops, the maker and model number were printed directly on the board. I’m not aware of any other names for OEM motherboards—just search using that exact model number.
