If there are components that will fry with no flow, then a flow
meter of some kind that will positively indicate that flow is
below a certain amount, and a mechanism to shutdown the system,
are essential for unattended operation.

Don't worry too much about water expanding... :-)

But *do* be concerned about the potential for leaks, because the
chances are fairly high.

Which is to say, I would *not* water cool a critical system
unless there is a standby system ready to replace it in the case
of failure. Hence, if it would take a week to get your system
back in operation if this particular box was totally destroyed,
don't water cool this particular box! If you have two computers
and can live without one for a few days or weeks, go for it.
