The 4ms mixer works perfect with the Intellijel case and products. I currently have mine connected to Intellijel’s new 1/8” XY 1U jacks. I’ve previously had my 4ms wired to the ins/outs jacks on my 7U palette. You could also daisy chain it to a mixup with no issues. The pin diagrams are available in both the Intellijel and 4ms manuals.
