Mineral oil is good for overclocking, if you use enough of it, but I chose to use a 2.5 gallon tiny tank.
The Puget kit is 5 gallons, and with proper planning of the path of oil flow, it can be great for overclocking
But only if you have radiators!
Yeah, I watched Linus's Puget mineral oil PC. Still, your PC looks great. :)
