Having had a play with both Supermicro and ASRock Rack boards for workstations (admittedly, only H12's so not the "most recent" but from my cursory glance and newer boards, nothing has changed that much), SuperMicro board feels like they were made in 2005, not 2024. It is ridiculous in fact.
* No support for ACPI sleep. In 2024. Seriously.
* No support for 4 and 3 pins fans. 3 pins are 100% speed all the time.
* IPMI web interface straight out of 2010.
* NVME placement prevents you from using heatsinks.
* Tons of opaque jumpers on the board, with no board labelling.
The ASRock Rack equivalent board is amazing in comparison.
