Useful for a hybrid approach though - the big problem with liquid cooling is
that the fluid and/or any condensed air vapour gets to flow inside a case
with (at least theoretically) swappable parts; difficult to arrange that
nothing requires either disconnecting and draining, or risks puncturing a
fluid carrier. By using purely solid-state components (and some sort of
thermal carrier paste) you could arrange for even hot-swappable (not an
intentional pun BTW) components to be able to pump their heat to a thermal
element on the outside of the case, which in turn is threaded with coolant
pipes for a fluid-based system to expel heat to the outside of the building.
