The box is tiny, much smaller and lighter than Calcifer. It has a shiny black exterior, which I like a lot. Unfortunately, it has only place for a 2.5" HDD, so I couldn't plug in Calcifer's HDD and be done with it -- I had to do a re-install of Ubuntu.
The system is pretty responsive. I'm quite pleased with it. Video is still choppy though -- but at least it's possible to identify the video, which was not even possible on Calcifer.
