I wonder why you switched and not use your 16-core PC? did it somehow broke or do you just like the benefits of a minipc?
I recently (8 months ago) replaced my 10 year-old laptop. The only reason I retired it was because the display was starting to go.
So I bought a second-hand workstation-class laptop with 6 beefy CPU cores and kinda wish I hadn't. Overall I want to like it but the battery life is abysmal, it makes a lot of heat even when fairly idle, and is a bit heavy due to the large heatsink inside. (And that's without a dedicated GPU.)
If I had to do it over again, I would trade it for one with a weaker but more power-efficient CPU.
