There is one company that sells sealed keyboards for industrial and kitchen type applications. I think I saw something on Slashdot about it a while back, but that is a start for hostile stuff. So you could do something like put the computer in a cabinet in the kitchen, run extension cables to outlets flush on the countertop for the sealed keyboard and mouse. Then perhaps mount an lcd panel from an old laptop as a monitor beneath a piece of plastic embedded into the countertop. Should protect from most problems that way.
