Got my hands on a True GDM-37 cooler. I took out all the fluorescent lighting, the stock temperature controller, and evaporator fan.
Replaced the lighting with remote controlled RDB LED strip. This is in place of the marquis lights, and interior lighting. Also added it around the perimeter of the upper evaporator cover.
Replaced the 120VAC evaporator fan with a variable speed 12VDC fan.
Replaced the temperature controller with an Inkbird 12v ITC-1000.
Added a 1" X 20" 100w Watlow Silicone Strip Heater.
All the wiring is point to point on Phoenix Din Rail terminal block components.
All the 120VAC is down on the bottom. The upper control panel that handles the temp controller, fan and lighting is all 12VDC. There are two relays at the bottom with 12VDC coils controlled from above that do the switching for the compressor and the heater.
Also making a custom marquee which will be backlit by the LED lighting. Also made the control panel and graphics. The frame for the marquee and control panel is "Frame World" EX-67 aluminum extrusion.
