The new EPCY 9004 CPU's look like a great option for a low(ish) power build.
actually i’d be looking at 8004 which should hit retail very soon. Should be even more efficient. Either way, both will outperform any v4 system. Don’t worry too much about the 200W, i’m sure you idle at 100W each node now. Not only does Epyc idle much lower, i doubt you’ll be hitting 100% cpu usage. No experience with 9004 yet, but i love 7003.
