Use of waterproof container for FlightView

I recently purchased the Flightview package.
Has anyone put these components in a waterproof box?
I am going to install them in an Amphibian aircraft and would love to protect them in the event of water ingress.
The real topic is “will the computers overheat if put into a sealed container and how much heat needs to be dissipated for each FlightView package”

Any advise appreciated.

As the Flightbox uses a fan for cooling, I don’t think a sealed box will work. Mine, with the vented box, reaches 85C on the glareshield, when into the sun.
