In our new apartment the internet connection is located in the closet/metering cupboard in the hallway. right from the start I had also placed server in the closet close to the modem/router, only thing was it was standing/balancing over main water inlet. So this was something that had to change very quickly.
H-Squared has some nice products all focused on hanging your Apple equipment on your wall. This one for the Mac Mini is called the Mini Mount. Fixing the plate to the wall it self is easy, just drive two screws into the wall and you are basically done.
However fixing the Mini itself to the Mini Mount proved a bit more troublesome. I ended up bending the plates for the locking mechanism outward so it would fit over the locking pins. So it wasn’t as simple as the instruction video on the manufacturers site led me to believe, but nonetheless when it is mounted it feels very sturdy and reliable.
