My father actually made a watercooled computer in the late 90s and early 2000. He used both conventional water cooling and peltier elements. The latter one actually produced snow inside the computer case. Of course it didn't exist any kits as it do now, so he made everything him self. I still remember the water hoses in the roof going from the cold water intake of the boiler to the computer for a constant cool water supply. He used this when he overclocked the Celeron 300A to about 600 or 650MHz. Over a 100% increase in speed. Sometimes I wish the equipment wasn't thrown away in the bin. Would be cool to rig it up again.

Wait, so your father's computer actually had its watercooling system hooked into the house's plumbing? That's awesome. 😁

I can't see using it on a machine that is too old. How much can you realistically overclock a 386 or 486? Liquid cooling would just be a waste.
