Is there literally nowhere else you can put your computer to keep it out of the smoke?
I live in a 2 bedroom trailer and I live in the living room, with the heater soo no.
Put some kind of filter over all the holes.
Don't have a filter.
The PC was moved to another location until I get a new PSU, when I get the new PSU I'm going to keep the PC covered when not in use or if I'm in bed (which is always when the heater gets lit inside causing smoke)
