I like this design a lot. It reminds me of the PC Engine Duo-R. I also like the sliding door instead of the flip top due to wear and tear those designs sometimes suffer. If you've ever owned a Dreamcast or PSX after much usage the latch begins to weaken and the plastic hinge can break. I think the ridge design is meant for you to grip the door easily and to show less wear on the left side it will slide over.
