And as far as space is concerned, I was looking at one of the pictures on the wiki and the piece holding the hard drive in on the far right seems removable. I've done some modding on iPods, and that piece seems just to hold the disk in place. I'm thinking it could be removed, freeing up a quarter inch or so, and held in place with a different, smaller piece of foam padding if necessary.

Edit: Did some digging into the forums, looks like this post is pretty redundant after all. Going to email Savannah Systems about the adapter they are working on. All right, guess I'll let this die. I'll post a new thread if/when they release the adapter (doubt I'll be the first though), or if I get a new self-contained adapter rigged up (hopefully make a post with detailed, photographed instructions).
