If someone wishes to run multiple instances in a DAW with other plugins that's a different question - more hit and miss depending on the load. Also using the multi simultaneous instrument features may eventually prove taxing with already marginal processors. 

A more powerful desktop i5-i9, or AMD equivalent or M series Apple is a worthwhile investment with more headroom for the future if it's a daw system.

First I thought to buy a mini pc,but this caught my eye. This would be practical bc it has display too. I'm building a simple solution for my bedroom (midi keyboard, active speaker, and Chuwi hi10 max. This set will be only for playing pianoteq live. Does this have enough power for max polyphony with low latency?

Should be. I've seen other n100 setups tested and their latency is fine. The n100 is a fairly modern chip, and sips power.

Provided the design has adequate heatsink airflow cooling for the CPU it looks more than capable, on paper. 

Try both WASAPI and ASIO - don't just assume the latter will perform best.
