I'm now using a 104hp 7U perfromance case and would want to limit all my useful, important modules for performance and travel inside. I wish to know are there any advice on disigning this size of rack and how to utilizt the space.
This is the rack I'm currently using (The third row is a 4ms 64pods, which I use for light travel and jam):

And this is my current plan:

I wish my main case could take charge of most techno and house performance and still provide me some space for doing ambient. The 4ms is mostly as a portable option for me to take some out and go to a park for a simple jam.
Some point I'm hestitating:
1. Shall I remove the BOC+SED and replace the combo with a doepfer 111-6 synth voice? The rides in the storm modules sound good but it just takes too much space in total (20hp, comparing with 10hp of the doepfer one).
2. Erica synth Black Hole DSP2 sounds good and I really like the knobs, but still it is a little big large. I'm thinking to change it with a Mimeophon, or a granular effect like Mojave or Beads. Which option might be better?
3. How many mixer is needed? One cockpit would not satisfy all the need. Can a VAC mixer solve the problem? or should I get another 1U small mixer? (I'm not gonna buy any large performance mixer until I have two intellijel case)

Feel free to ask the product I've owned if you're interested.
