You've made some changes to the rack above. But those changes aren't reflected in this thread.
If you're using the modules as place-holders... umm... okay.
But there are some issues in your approach. The first thing is power and HP. The more modules that you cram into a smaller space, the more you'll be dealing with issues like heat, overtaxing your power supply (supplies), and simply running out of headers to plug everything into.
If your end goal is to create an advanced system, I would first concentrate on finding a much large case or multiple cases.
The 2HP modules tend to run deep because they are only 2HP... you'll end up compromising on features since there's only so much real estate in two rack spaces. Again, those micro-pots are going to be an issue even if your fingers are child-like in size.
Populate your rack with units that you'd actually want. It's a bit like designing a parking lot to only work with sub-compact cars then expecting a full sized vehicle to be able to comfortably park in there. My opinion is that you're setting yourself up for an expensive lesson in Eurorack if you pursue your ambitions down this path.
