Thanks Garfield,
I have a 104 HP Palette case that I plan to use for the Ground Control Sequencer, Queen of Pentacles and 1u support modules. My build plan so far:
I also have an Endorphin.es Shuttle System on the way! A trio: Make Noise Shared System, ALM Busy Circuits Super Coupe and Endorphin.es Shuttle System should be perfect mobile rig for me with the OP-1.
