Being a Mac person I'm well aware of the liquid cooled G5 (especially the quad
) but I've never owned one. Though a few months ago I was playing around with an HP workstation and was surprised to find HP made a liquid cooling system that could be installed in place of the standard heatsinks and fans and it takes about 5 mins to install.
That got me wondering about other systems that came with stock liquid cooling. I'm thinking more desktop/servers than huge supercomputers with liquid-cooled doors
but post anything that you think is interesting.Apple Power Macintosh G5 Info from everymac.com.

Dual Opteron workstation based on a slightly modified Tyan S2915 motherboard. Liquid cooling was an option on higher spec'ed models and since the water blocks, pump, and radiator are all a single unit, it can be added to any system. With a BIOS update 2.8 GHz six-core Istanbul Opterons are supported.
I had the HP maxed out with twelve 2.8 GHz cores and the liquid cooling system but downgraded it to the original dual-core processors when I bought my Mac Pro and put the standard heatsinks back in. Here's some shots of the cooling system. The radiator replaces a large rear case fan and the rest of the unit sits over the processors. I never did any serious testing of temp control and noise though the system was quiet and the CPU temps around 55-65 C under 100% load for hours.
