A couple of things,
First why the additional white panel on the back, and I assume the enclosure for the CSXCV is to keep it from falling?
Second, are those split rings run of the mill key rings, or are they intended to be load bearing?
The white panel on back: they velcro onto the back with some padding, and protect the displays and buttons from bumps and knocks. They also hide the temptation for electronic-addicted kids in case they think they can get on the internet via the back panel :-) Almost all of my shoots are on location, so my beloved 640's get moved around a lot. Since I'm a CC user, I rarely have need to look at the back panels.
The acrylic enclosure is a little bit past the "experimental" stage, and allows me to just leave the CSXCV's in my 3 Einsteins as they travel around in my bags with me. They offer some protection against bumps and knocks, but they are more about saving every set up minute possible when on location.
Neither of these looked super polished, but the functionality is worth it to me.
The key rings are load bearing, but they are not your typical ones. I can't remember where I got those - they are extremely strong - and there are two on each of my 3 Einsteins. I've tested them with 50 pound loads, and there has not been any bending.
