Mine is primarily a 4u server, in a rack. That’s screwed to the wall (for added stability).

They’d need a couple guys to unrack it. It’s in the garage I rarely ever lock, behind the cars which are more valuable and easier to steal. Behind the much more valuable tools.

Garage does get warm in the summer and cold enough in the winter the fans do funny things.

Anything important gets replicated to another location as well as backed up to a cloud bucket. So if it got stolen it would suck, but not the end of the world.
