Okay, While working on the case I had a very Zen moment and re-laid out the display board. It now only has 4 digits  and a very small touch keypad.

I also added a real-time clock. I am working at hardening it so it can survive me going on vacations. This means it has to handle a reboot and not have access to any of the sensors except that one that is attached to the thermostat itself. The RTC removed the dependency of getting the system time from network.

The case was made out of 1/4" cherry wood that was milled using my zenbot cnc. 

The photos do not show the super cap that is used to keep the time
