I finalized the front of the enclosure and replaced or added a few knobs and features as below. 

I'm still thinking about what I can do with this power button on the right. It triggers a pulse switch, so maybe I can make an emergency stop or a hold button ? 

Next steps are to finalize the wiring of those features, then I will move to the back of the case to add the connectors for the motors/spindle/lasers and the power supply outlet.
