I'm not sure how helpful this post will be, but here are some links that might be relevant:
The first is from Minox in helping someone troubleshoot, I link to it because the guy seemed to know what he was talking about:viewtopic.php?f=8&t=627&p=2675&hilit=take+apart#p2675
Incidentally, from the beginning that post is about left half problems.
The second is from a user who did open a Touchstream, and it only links to the original post (which is in the original fan forum, and may eventually be deprecated):viewtopic.php?f=2&t=269&hilit=take+apart
The third is that user's original post on the new forum (in case the original post in the original fan forum gets deprecated):viewtopic.php?f=3&t=268&p=1318#p1318
Sorry none of them have pictures or step-by-steps, but good luck if you do indeed require disassembly. If you are capable, posting a writeup could certainly be helpful to other users. Also, for the record, you may want to search some more, I really think I saw some disassembly pictures at some point.
