You have probably seen them around or at least in the news - big boxes housing power supplies, networking equipment, etc., like so:
I know that box is from TotalRecall, but they evidently sell an end to end offering, not simply the housing / enclosure.
I presume many integrators just fabricate them individually but am wondering if there is anything more COTS available?
A member is looking to have a portable kit with cellular, etc. that they can move around as needed.
