When I was living in Botswana, on the edge of the Kalahari Desert, my long-suffering Quadra 950 lived on the floor atop two bricks in a water filled trough with a finely perforated plastic sheet sealed with gaffer-tape.
This stopped the ants making a home in it, kept the resident Manitis from being sucked into the vents and withheld the Kalahari duststorms which would permeate every orifice (Domestic and personal!).
The trough was three inches deep and needed topping-up every 24 hours.
In 35-40 © degree temperatures, I always wondered why my "Big Meg" never blew a fuse from perspiration.
Nonetheless, when I left Africa, my 950 arrived here (UK) with about a quarter-inch of fine red-dust 'stuck' to the main board and most other vital components; a clogged floppy and about 500 starved (dead) ants!
Despite living in water and being infested by mother-nature's tribulations, my 950 eventually died when my girl-friend over-loaded the power socket with her hair-drier!!
Its a true story which proves that Macs can cope with just-about-everyting EXCEPT a woman's vanity.
Best Wishes
