Let's hope someone's making them into a nice little section on the ADI homepage. Each of those showcase "messages" would really look nice as just a simple thumbnail web page.
I learned a lot about how I should set up my own ADI equipment from the "showcase", but IIRC, it took a lot of searching to find your clever idea of the false air return to conceal the modules.
I like that register-cover idea for two reasons. It cools the equipment and it gives waist-level access to the modules. I've been angsting about whether to mount the SECU module and others like it using DB-25 connectors so that if a module fails, I can just swap it out without having to rewire every lead. I still haven't decided how I am going to handle it.
