You’re right, the Threadripper Pro motherboards look exactly like what I’m looking for whereas the server boards for Epyc will bring considerably more trouble. On the other hand, the 3rd gen Epyc is a new chip released early this year and my understanding is that the TR Pro and Epyc are very similar in many ways, but with the Epyc I’m getting newer technology (Zen 3). I’ll be reading through this thread to learn a bit more.
