I am glad you have a clean computer... I believe the excessive dust can
interfere with convective airflow which cools the chips... and hot chips
mean shorter lifespan for the motherboard.
While repairing customers computers, I have been using a 'reversed vacuum'
for decades to blow out the box, or if it is really dirty, I gingerly vacuum
the heavy deposits before blowing it out. I suspect that the normal vacuum
can suck out a component or loosen an wire, or even create a static charge
that may damage the motherboard. Blowing does not have this effect, and you
don't get as close to the board with a blower.

Subject: [CGUYS] Cleaning the Inside of a Computer
My iMac is about 4 years old, and I think that the fan noise is louder
than it was originally. I want to open it up and vacuum the dust out of
it, but I recall reading that this may make a static electrical charge
that could ruin some semiconductors. I would like to know if anyone has
personal experience with this, either good or bad (I was going to write
positive or negative, but...); or is this just an urban legend?
