Huff had a mid-sized rack, probably 16 spaces, but you are right, there is no telling what kind of uber gear his signal was running through. It was quite a while back, but it was when I was talking with CAE about some gear and they mentioned they were working with him.
Another source you could contact are the guys at Techstar in Nashville. They put together rack gear for some heavy players and I've seen lots of CAE gear in their products. They are easy to contact and talk with as well. I know they have a website but you'll have to do a search.
