I recently upgraded my office desktop into a 2P EPYC system. tts just munching everything I throw.
you have to go through companies like thinkmate, supermicro, server direct, etc. you can't just buy the processor and boards off the shelf.
You can buy the parts indiviually and build yourself (way cheaper) unless you find some incredible deal for a prebuilt or don't have time to fuss with putting it together.
back when i made that post there was 1 single socket supermicro board for sale on newegg at the time from a third party seller, nothing else. good to see it's shown up on newegg so that everyone has access to the hardware.
