I bought a bracket for my old mac mini, and it doesn't work with the new mac mini with a dock under it, so I just made a new one. It's a bit of a tight fit, I think the little overhangs that hold it in place could be a little smaller, and I ended up just breaking off the piece in the front because it wasn't necessary and was holding it too hard. Otherwise, it seems to work quite well for me.
