Calculation box on the Playstation VR?

When I look at the unboxing videos for Plastation VR, there's always a calculator box where you can push part of the box back and forth on a rail to hide the cables. That's different with my computing box, it's just a compact case… Do I have an old model? Or a new model?

There are only 2 models. The device number I just do not know from the head, but is certainly on google.

still believe that the newer model made it possible to hide the connections.
