I think that putting the computer higher than the pump can push is

water lines, instead of pushing water out into the electronics.

The drawbacks of this system are that you need to
prime it, and that a bad
enough leak will disrupt the coolant flow, so you need to monitor the flow
rate or have a decent thermal shutdown mechanism. You need that in case of
pump failure, anyway.
Why not simply use a standard sump pump? Most such pumps can push a 15 or
20 foot head and don't need to be primed.
