It was my initial thought since X399D8A-2T mobo (X399 but has IPMI) existed for TR 2000. But they changed chipset for TR 3000 and TR 3000 don't offer 16 core SKU (it's enough for me). I also found that even TR 2000 build isn't much cheaper than EPYC because it needs ECC UDIMM that rarely sold cheaply rather than ECC RDIMM. So finally I go for EPYC Rome.
