I was just sharing my personal experience. Unfortunately accidents happen so I agree with you: better to err on the side of caution than be sorrow.

My best choice would be to use high quality barbs,good strong metal clamps and thick tubing. Then of course I would not normally leave my computer on during my absence but just in case the afore mentioned precautions should suffice.

Getting back to my watercooling rig I am curious: have tests been conducted on watercooling setups do determine wether it is better to keep the circuit flowing 24/7or is it ok to have the pump going on and off?
