Shakespeare thank you for your advice. It was really helpful. I actually replaced Maths with Quadrax in my setup. I saw the youtube walkthrough and it is a really amazing module. I would like to ask you a question. In my setup, I have the intellijel audio Interface II which has 4,4cm depth and the case I am planning to buy is Moog Eurorack Case, which as 4,82cm almost 5 cm. Do you think it will fit or it too tight?
