This might void your computer’s warranty but it’s cool as hell! Using a $315 kit from Puget Systems you can submerse the innards of your PC in a case filled with mineral oil colored blue by a light to make your PC look like an aquarium. The mineral oil works to dissipate heat away from all the parts and keep your computer cool. And as long as you have an SSD hard drive, your computer will still work just fine. You can even add a bubbler for that full aquarium effect. Awesome.
