Dunno about you, but I'm not mad keen on having multiple kilograms of weight hanging off two 1.6mm thick fibreglass boards. The weight saving, the noise reduction and the thermal improvements allowing higher and more sustained boost algorithms easily outweighs the 5 minutes of "faff" of slapping some rubber hose on some barbs between a couple of radiators and my motherboard assembly.A lot more faff for not a lot more payoff imo
Any water loop that moves past the function and practicality of EPDM hose and barbs is a project of aesthetics and craftmanship. And that is absolutely not a "faff", that is a joy.
