I am still a strong supporter of the original ABS plastic Lantern case with the clear non-ABS plastic) cover. I could always fit a CHIP + all the other items inside. With the Dreamcatcher, there is a bit less room, but everything still fits. The box is completely portable and easy to carry around.
I have found the ABS plastic between the antenna and the active board is a good EMI reducer. Water proofing has been a non starter for me because of heat build up inside - - a completely closed box can't handle the sun. To wit, the old plastic garbage bag cover
Any way, are you looking at going back in the Lantern-enclosure direction?
