Don’t buy a consumer board for a server unless you aren’t using it to store important data. Like, say, a GPU cloud gaming or Plex server would be fine on consumer hardware ifyouf dont need out of band management.
Also ECC RDIMM is much easier to come by than ecc udimm but only works with epyc or Xeon chips. I say if you’re going for storage then definitely buy enterprise gear and if you’re going for raw CPU/GPU compute you should be fine with consumer hardware.
If you just want am4/5 ryzen chips, asrock rack makes some good boards with IPMI.
here’s their x570 board you can browse their site and they also have am5 boards and they dont have three gimped x16@x1 sockets.
