If you're like me, you could open up the back of your keyboard and make a sandwich out of all the stuff in there. I don't recommend you eat it, but hey -- it's safer than bagged spinach. But let's say you need something a little more durable than your standard keyboard, because you want to shave and shower while you visit Hot Hardware's forum. Stealth computer has your NEMA 4x solution:
NEMA 4X rated means it's made for
"...protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, hose-directed water, and corrosion; and that will be undamaged by the external formation of ice on the enclosure."
Maybe you could tape it down to the desk top with your Nuclear Duct Tape.
