There's ASRock Rack boards with X470, X570, X670, etc. chipsets that take standard AM4/AM5 chips and have loads of server features like IPMI and ECC (I think that's already common on the AMD side). I managed to snag a 5950x to throw into mine but I was rocking a 5600G for a while. They're mATX/ATX too so they'll fit in a regular case and take a regular power supply - no racks needed!
