Yes that’s right. The website has the full product list showing all the back plates. As I understand it you order a case with one of your choosing, then can also order alternatives. There’s also video links on the webpage, talking about the case and putting it together. With the A500 backplane you also get a very cool Zorro II re-director board which lets you use quite a few A2000 cards with your 500 board - very cool.
