I wonder whether liquid cooling will ever become a real mainstream option.
I don't mean overclocker's paradise, like Apple attempted with the last PowerMac generation using a closed cooling system prone to leaks, but instead submerging the whole computer into non-conductive liquid, like
here.
Only in a much smaller box, suitable for home or at least workstation use. Submerge the hot components in a separated box (or case compartment) and have things like rotating-platter storage in another (air-cooled) one.
Submerging would mean to have much less interfaces to seal and non-conductive liquid would mean no harm to electronics, even if a seal breaks.
You would also need less space for the otherwise necessary airflow, so you could build even tighter housings (or should i say: thinner!

).
And with mass production the economies of scale would significantly reduce costs vs existing solutions.
Do i miss or overlook something in my assumptions?
