Very nicely made heat sink case. My only slight disappointment is that I needed to fix it onto a vertical wooden board, and without any pre-drilled holes for fixing to anything, I resorted to using sticky velcro tape. That worked for a few weeks, but when I last looked, it had fallen off and was hanging on by the power wire and the ethernet patch cable (it is mounted next to my router and serving a WordPress website). When I get some time, will see if I can drill and countersink a single hole somewhere in the base (I'm a retired aeronautical engineer, and don't believe in over-engineering anything!)
