I agree with the point about noise. I’ve been looking for a powerful, compact and silent gaming pc for a while ( with silent then compact being more important than powerful ). I don’t need a laptop - a Mac mini-like or slightly bigger box is good enough .
When I look around, gaming pcs are mostly about big and visible, sometimes reasonably silent, almost never compact, inconspicuous and silent.
To me there is a market for this kind of product, and it hasn’t been addressed properly yet.
Since I have so far failed in my quest, I now use GeForce Now from my Mac mini which is a good approximation of what I want.
