Wiring up the 12V DCDC converters. The enable wire gets its own ground return path for EMC reasons.
These power two fans each, and get really hot to touch. Therefore, I glued them to an aluminium length using thermal glue and thermal tape to insulate the converter from the aluminium.
Three of the LED drivers mounting on acrylic glass due to all the leads of the through hole components poking out on the back. These modules have mounting holes, but due to the heatsinks, there is no room for any screw head... I went for cable ties as a sturdy substitute.
