Dirt, dust will greatly affect a computer's life expectancy.
I try to clean my old PIII twice a year. Open it up, take outside and
blow all the dust out. Then pop the cover off the PS and give it the
same treatment. Clean all the fan blades with Qtips and alcohol as
well as the CPU heat sink.
ESD  procedures are called for but all that really amounts to is
putting a hand on the chassis before touching anything inside so any
charge you have built up is disappated through the chassis rather than
through a chip's gate.
Best of luck,
Mike
