$599 seems like a lot to me. You can get numerous older, much more powerful Mini PCs (e.g older ThinkCentre Tiny series) or even a base brand new M4 Mac Mini for that kind of money.

Admittedly, the 10G interfaces and fast RAM make up for some of it, but at least for a normal homelab setup, I can't think of an application needing RAM faster than even DDR3, especially at this power level.
