Welcome and I just built a mobile techno focused system with drums, bass and so forth in a 4u Intellijel Palette case. So far it works great. Here is what I put together to help you as a guideline:
First, some advice.
Ditch the larger Desmodus Versio and get the smaller Happy Nerding FX Aid unless you plan on a larger case. Also get rid of the Clep Diaz, Mimetic Digitalis, Horologic Solum, and 2HP LFO. Get a Pamela New Workout instead as it takes up less space, has 8 triggers and greatest clock in eurorack and good euclidian sequencer plus logic and random options for modular and great for drums.
Get a decent quad VCA and thank me later as well. I know that you like Noise Engineering but their modules tend to be on the larger side and not idea for a small case. I also recommend a larger mobile case like Intellijel 7u case that is still portable or a Tiptop Mantis case.
