Nah, I'm in there with Ronin...this would be better off in an Intellijel 7 x 104. There are some modules in the Intellijel tile format that can replace/better what's here currently, and also open space in the 3U rows. For example, the Triatt can go in favor of the 1U Quadratt. The Befaco Out would then get replaced by Intelljel's Audio I/O tile so that the case's 1/4" jacks are useable, which also takes the output pair off the front panel and gives you an audio input as well. Then you can also add a Noise Tools for a noise source, clock, and sample and hold, and a uMIDI for a MIDI interface...and all of those changes would up this build's game considerably, AND leave space for some more tiles to keep that trend going. Maybe Intelljel's Stereo VCA would be useful for controlling the overall output...or if you can scrunch things on the tile row a bit, their mono digital reverb...?
Otherwise, the module compliment is pretty good. Looks like you did your homework in VCV Rack pretty well!
