How to design an indestructible computer

It''s funny to see how people are dealing with computers... https://rinkworks.com/stupid/cs_abuse.shtml

But on the other side, I think that it would be an interesting exercise to design an indestructible computer. One that would survive if its owner will put it in the fridge to cool it down. After all, we designed computers that would survive to high levels of radiations in space. Why we wouldn't be able to design one that can be cleaned up with a garden hose?
