We have a machine at work that produces "20 mega-Ohm water".

Of course, water reacts with *air* to absorb various ions. (For example, 
CO2 disolves in water to yield carbonic acid.)

But seriously - computers work at 12V. The water's resistance would have 
to plummet to yield any meaningful current.

I would imagine a far bigger problem is water's viscosity; I'd think 
fans wouldn't like that...
