Well after a week or so off things are back on track and coming along nicely.
The cedar lining for the top, bottom and sides is finished. It's actually a separate box that sits inside the main cabinet.
Here you can see the 'box' within a 'box' with a gap for the insulation and wiring.

This is the start of the main control panel with the temp/humidity control as well as the fans, lights and a low water warning light.

Here's an overall shot
We're going to add the insulation and start running wires next week and then it's on to the back panel, the shelves, and the doors. We're shooting for a March 16th completion date but we'll see how things go.
