Worked at a county office last year where I'm amazed something similar didn't happen.
They had an order of ~150-200 laptops, all the same, and valued $300-500 if I were to guess.
Stored in the "cage" outside maintenance office, in the basement.
Not many people knew they were there, but a few did since they saw us transporting them all over.
The cage had a key that wasn't actually necessary; you could just reach through and lift up the pin, and get in that way. Common knowledge amongst the whole IT group, since there was only one key and we had to go there a lot.
There also wasn't much security-only me and the maintenance guy were normally down there, in his office (where we couldn't see who came in), and then half the time on the road to different locations. No sign-in process or anything. I managed the security cameras too, so knew that there wasn't one directly in there (but there were by the entrances most employees were unaware of).
Was my job to image them, but they were sitting there for like a month before I was giving the go-ahead.
Somewhere between 50k and 100k, not including everything else in that area, was just sitting there easily accessibly by a building of 100+ employees, and not one tried to steal them.
