I'm new to custom loops and have some questions.

Is EKWBs configurator reliable? I don't want to buy a waterblock and backplate only to learn it doesn't fit.

Does loop order really matter? I've seen some people argue about this and don't want to make a mistake.

Is primochill vue fluid really that bad?

Does reservoir size matter?

Nickel plated waterblocks or bare copper?

Is there any disadvantage for going with a pull config versus a push?
