I'm really interested in this too. I'm tossing up between something like this (maximum thread count but probably high power usage) or a Ryzen build (simple and low power).

That CPU has a TDP of 115W but I can't find much information on the idle power usage.

I would also like to see a write-up of the GPU pass-through setup since that's something I've been wanting to have on my local system for ages, i.e. vm host system => dev vm 1 ... vm N, Windows VM + dedicated GPU for gaming etc.

If I were doing a build today, I would be sorely tempted by Ryzen, mostly because it would be new hardware and the AM4 platform. That said, having a server board has turned out to be really nice for a lot of things, such as ECC memory and nice virtualization features. It looks like Ryzen has some issues with kvm passthrough so far[0]. My favorite resources are [1] and [2].
