Sweet as , my head wasnt leaking so I used a tool that was like a pop rivet but with a long m4 thread in the middle and nylon screws to attach the power supply to the chasis. Being a plumber i used detail tape from our bytnol roofing system to isolate the supply. Interesting material the detail tape, expenive as a roofing product, maluble and sort of like a mastic compoud . The first time I saw it i grabed a bit as it looked useful .
