do you keep any insurance? Rental/Property insurance covers theft and destruction by vandalism, usually.
Also, Word of advice, set up DIY security. couple of magnetic sensors on doors and windows. a Super loud buzzer, and if you add a low-powered device such as a Arduino or Raspberry-Pi, you can even have it email you alerts and take pictures.
Doesnt completely stop it from happening, but it means evidence when the police get there.
PS- Watercooling, and 4U E-ATX rack case(with bolted rack). never have have to EVER worry about that again.
My ex-wife did that, her and her boyfriend screwed them selves out of alimony. Because i caught them on camera using GNU-Motion.
(i would of preferred jail time...)
