You can find someone to build you a nice wooden case for it that will keep your rear connections from getting jostled as well as protecting the front knobs. Some of my friends from St.Louis built one with little computer fans attached to keep the thing cool.
I know Ben used to build the boxes and Van also but I don't know if either still does, shit I haven't seen or heard from Van since Phish stopped touring so I'd hit up Ben
If not I have seen people use wire shelving to achieve the same thing. Check the Oade archives, I think there are some pictures up.
Good luck, that's a great piece of gear, I remember the first time I ran one with my rig. I was just so amazed at how much more I liked my tapes. I knew that the ad1k sounded good but until I heard what it sounded like with my rig I just had no idea. Sold my Dmic20 about a week later and bought a 500e just to get that Apogee sound...
