Totally get it. Now, if this is a concern holding you back, think like an engineer would and figure out a housing that would be weather proof, but allow ventilation and cables to come in and out, and still look decent…Correct, the concern is with water- not physical abuse(dropped or bumping it) and a decent one should shut down if it's overheating
In a prior role I was an engineer and designed digital signage systems. You’ve seen my work. I guarantee it. Stadiums. Arenas. Wendy’s. Nike stores in the malls. My designs went out to enterprise customers. I’d design it. They would buy them. My company would put them in every single store location nationwide.
I designed an enclosure to hold a 65” lcd display, a 1u rack mount computer, mini network switch, And some other gear. All was good until stadiums wanted to buy it and put them all over…open top stadiums. So now my design had to be upgraded to have beefed up cooling, a heating system, thermostat, and all the vents needed to be weatherproofed. It was all new to me but I figured it out and they are still in use today 10 years later
Bottom line. You sound resourceful and intillegent. A diy crafter. Build an enclosure or find a premade one. add weatherproof vents. Wire pass throughs with grommets / rubber foam seals. And you can easily build it. Heck with low wattage fans you can have the battery backup station power it’s own intake/exhaust fans
