[May 6, 2020] I used an Erica Synths 6u x 104HP case for interactive controls. The Tete is on order, and I keep fiddling with the layout, but there's a good deal of expression potential with this case. I use some flat 6ft ethernet cables with the multicore to patch over to the main synth rack, and tend to use external unbuffered mults for triggers and gates. They're cheaper and they don't take up rack space. I could probably use more cross-patching capability between racks, but it is what it is.
