I thought it was dusty in my computers. If it is as bad as you say you
may need to invest in a computer that is designed to survive in an
industrial environment. Be prepared to pay for it though. Short of
that be sure that you keep your computers off the floor, that alone
significantly reduces the amount of dust build up. Also use a case with
a filtered inlet fan and clean the filter often. Just be sure your
inlet fan pulls plenty of air to keep up with the exhaust fans, other
wise the exhaust fans will suck dust in every little hole in the case, I
have seen them even pull air in through (yes through, as well as around)
the CD-ROM drives.

I use varnish for boards that may get wet. With a computer
motherboard you have to take care to keep the coating off the
connectors and IC sockets - varnish can wick up into the spaces in IC
sockets and cause problems.

Works well for corrosive environmental conditions or where moisture
may condense on the parts.

I never clean my pc out ever between upgrades and it never goes wrong
with dust.

If your in a dirty environment then you maybe need to do some air
filtering before it goes into the PC.
