I've never seen or heard of them. While I like the idea, and the pics look very nice, I see a few significant problems. Kennyt hit on the cabling issues. The pics of their cabling look great, but I can't imagine it coming out that perfect. I think heat is another issue - even if power amps aren't included in the rack. Finally - the cost - haven't seen the price list, but I can imagine what it looks like, and it wouldn't be worth the investment to me.
That said, I know we're all different in our wants/needs, as well as our rigs. So these may work great for others.
