>Comes in a really stupid case that I cannot for the life of me see how you open. I can see a hinge but it defies all attempts to open it so I am now going to break the stupid perspex box.

I did the same thing. There are actually threads on forums related to exactly the problem you are having. I think there is a little tab or piece of plastic on one side that you remove by peeling or pulling. Then the case will open. I just took a pair of aviation snips and took it apart. That works too.
