I hear what you're saying. It is pretty clear I will outgrow this case. I'm going to ease into this and buy a subset of the modules, spend some time with those, and re-evaluate. Maybe I'll completely change my plan or decide I don't even want to proceed (I doubt it though).
I wanted to have a solid plan for fitting everything I needed into that case. It was going to be "the rack". I think this was partially to establish a maximum budget on this because it is pretty darn expensive, but it's leading to bad compromises like buying a module I probably won't like to "fill in the gaps". The fact is I'll be spreading my purchases out over time and at some point I will have the budget for more if I want them.
I think I may stick with this case though. Maybe it's stupid but for some reason I like the 1U form factor, and this case seems relative easy to transport, which is a factor for me. You can actually join two of this model of case together, so my plan is when I outgrow the first one I'll buy another (probably one horizontal and one vertical which seems like a common approach?). If I'm seriously thinking about buying the Disting, it might mean it's time to get that second case!
PS - Yeah I had Stages in my virtual rack at one point. I think I will pick one up eventually. Thanks to Softube Modular and VCV Rack I am already a Mutable Instruments fanboy.
