In an effort to locate power closer to a 5v pixel roofline setup, I'm considering putting power, an F8 distro and Falcon smart receiver in an ammo box, and securing it under the soffit of the second story. Is this safe to do, and does anyone else do it? With only one Meanwell 350w PSU, in say a MTM-30 ammo can, do I need active (or passive) ventilation? During Christmas-time, load on the PSU might hit 60%, with average ambient temps < 30f. Other times of the year, PSU would be ~15% load.

Lastly, assuming this is safe and acceptable - if anyone has any recommendations on how to secure it (siding and soffit are both vinyl), that would be helpful as well.

Thanks for any and all insights!
