I finally got my broken-hinges-and-displayless TiBook back together with newly acquired LCD. Here's what I've got so far . . .
Cables were easily long enough to wrap the LCD to the back (bottom) of the 'Book. It's just taped together for now, but as a proof-of-concept I'm very satisfied.
The entire package takes up the same volume as any closed TiBook, and it's a very compact and 'clean' shape with which to work. It could be hung, stood, cased, or with whatever one's imagination creates. All in all, a very good starting point for a very 'special' Mac.
