Yeah I agree that a manifold is the better solution.... I made this temporary one for mine.
I'm not overly happy with the "Barbs" & plastic pipes, so when I'm happy with the layout I'll be using pneumatic fittings throughout. They are rated a 10 bar and can be easily disconected if required.

Yeah copper can be a pain in the ass to work with. It's not too bad when you know what you can get away with. Does polish up beautifully though
All the retaining holes for the copper baseplate were drilled & tapped with an, (easy to snap) M2 tap. much care required.
Let me know on the GPU block project, I'm always keen to learn new tricks
