I am playing with the thought of doing a copper pipe sff pc build in the louqe ghost s1. (it's in stock in Sweden) Ordinary parts, but with copper tubing and all the bends done with plumbing fittings. Will 16mm fittings fit 5/8 inch tuping? Those are the only ones I can get where I live. Those will be for connecting to the parts. And, as said in the title, where can I buy the pipe? (btw, type k pipe is usually branded as 1/2" pipe, but that's ID, OD is 5/8")
