Those are in Australia, Chip.
One of them looked like it was built in a PVC chassis, but I have no idea what goes into building an OpenVario. Prefer to support the people that make stuff for us.
You could probably keep an OpenVario or any other instrument nice and cool by putting it in the panel of a JS3.

Didn't realize there was much OpenVario action over here. Haven't heard anything about heat problems.
