Don't know a place to get it prebuilt, but building an EPYC "desktop" can be a lot like building a TR one. There are ATX server mobos. TR4 coolers should work with EPYC; Noctua explicitly says theirs do, and the physical socket and TDPs match. You might want TR for the higher frequencies, though. I guess you could use EPYC for a very expandable 16C machine, or to pay a bit less for lower clocks, though I don't know if it ends up worth the fuss.
