Yeah - you do indeed have to start somewhere
you know I think those cases (anything under 6u /84hp to be honest) should come with a warning - "buyer beware not suitable for a starter case, unless you want to buy another one in a few months" - imo great for a dedicated and focused single purpose once you know what you are doing - ie to house a few controllers or a mixer or whatever
but anyway good luck and once again enjoy
