Server motherboard featuring two EPYC 7003 slots and a total of 16 DIMM slots. EEB is the form factor (305x330mm).... ASRock ROME2D16-NL Rack dual EPYC 7003 compatible motherboard with 16 DIMM slots
The vital minimum for server... It lack U2 port and high speed LAN... So you will have to populated PCIe port for a real use (and bother for 1U use).
I agree - dual 10G ports would be very nice additions. The 1U form factor is not a big issue for my purposes but it can be a good thing to have. If you could ever find the third generation EPYC CPUs available this board might have promise.
