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.
