your computer (probably) does not have enough fustiness, nor is it truly crufty, unless it is from 1979 or before. I must have old capacitors full of PCBs, charged to voltages so high that the cracks in the age-old insulation show bluish as the extravaganza of pre-ionization gets underway! When they explode, PCBs will spew everywhere and men in white suits will have to remove the topsoil and carry it away in yellow bags.
