Edit: you're going to need VCAs if you want to use those envelopes to shape sounds.
I had Veils in here but I pulled it out thinking the 1U Quadratt up top would handle things. Am I misunderstanding? Guessing that would be the justification for the bigger case.

quadratt is a quad attenuator - not a vca - veils is an excellent choice btw - not only is it actually a voltage controlled amplifier - most vcas are technically voltage controlled attenuators (in that their maximum gain is 1) - it has so much potential gain that it can be used to amplify external signals up to modular levels - it also has 4 of them and they cascade so can be used as mixer (or mixers) - plus it has the ability to add an offset voltage on each channel, is dc-coupled in that it can be used for both audio and (just as importantly) modulation and is variable between linear (more useful for cv) and exponential (more useful for audio
I'll second get the bigger case - personally I would recommend a tiptop Mantis - 1u is seriously overrated imo
I'd also suggest Maths, if you can find one, as it has one of the best learning resources of any module - the 'maths illustrated supplement' which is probably the best primer for patch programming and modular patching in general
I try to think (loosely):
sound sources < sound modifiers < modulation sources < utilities
this generally gives the most variety for money invested - at least in my opinion
hope this helps

Utility modules are the dull polish that makes the shiny modules actually shine!!!
