Pure water (distilled, deionized water) will not conduct electricity. We consider water to be electrically conductive because of the ions created by dissolved minerals in it, which are almost always present in water. Unless you handle the distilled, deionized water very carefully, odds are pretty good that it will come into contact with something that can dissolve in it to produce ions. This "something" can be metal pipes, or even gases. Polymers, like PEX tubing, should be safe. In a typical water-cooling system, where the water doesn't come into direct contact with the electronic components, its safety depends on the durability of the materials used to contain it. and the liquid-tightness of the connections. For a boiling system like Jim Lux brought up, it's very unsafe, since odds are good it will come into contact with something that will produce dissolved ions in it and make it electrically conductive.
