A few thoughts, not a comprehensive answer. If you have a pedal board you like, I think it's best to use that at first, unless there is an effects module that you can't match outside the rack. Maths is indeed big for a case this size and if you're using it primarily for envelopes and LFOs, yes, there are smaller alternatives. Common wisdom on semimodulars that come with cases, like the SV-1b or the Moog DFAM/Subh/M32, is to leave them in their cases. That gets you space for modulation and utilities. There are smaller Elements clones, but ergonomics will be worse.
