Yeaah, not saying that’s impossible but with two left hands and a bit of disability sprinkled in that’s just about what I don’t do myself. So I resort to purchases. And with less space in European cities’ housings (which is - to begin with - the issue with not being able to put the pc a room away) you can also not just put a big wooden box anywhere.

Oh and also even if they kid about this in the beginning: if this does catch on fire the insurance won’t like that at all.

So sadly lots of reasons not to do this.

If however I at one point can put the pc a wall away it would be cables through concrete and pretty silent.
