The underpressure is a design feature (to minimize damage from leaks). I'm

computer the water ends up in the reservoir, not in the computer. The sound
of a leak is also pretty obvious.
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.
