the smell being dust, or ozone? Working in a computer repair place when i was ~19 ruined my sinuses forever. I have a lot of old hardware kind of sorted in cabinets, and whenever someone needs some old hardware i have to either dust mask or take an antihistamine.

So asking me for something to fix a broken old thing usually involves me making a cross face, handing you whatever it is, and then taking a nap after washing my hands twice.
