I wanted to ask the more experience of you here about how to go about testing the loop. Should I
1) Leak test the loop in place in the PC overnight (with everything off of course)
or
2) Leak the the loop out of the PC overnight, and then build it inside the PC and leak test for a few hours?
I'm guessing, that if there are any major component problems, the leaks will appear even when it isn't inside the case, and that's the main reason to leak test, beside checking that my fittings are secure?
What do you suggest?
