AIO water cooling and heatsinks are so last year. DIY Perks takes a brand new i9-13900K processor, mounts all the major components with water cooling bricks, encases the entire PC in a waterproof acrylic tube, and runs all the cooling through external copper tubing. How does it cool it? Using a pond.

And it turns out to be extremely effective – reaching only 20C (only 5C more than standard) at full load after an hour. Dang.
