Don't know exactly how relevant it is, but Ransai has a page about modding here, and one specifically on microswitch removal here. (Sorry, couldn't find anything similar looking over DASC's site to see if the process was the same.)
I was sent a video a while ago about how to remove the microswitches, and I decided to upload it on Youtube just for this thread: http://www.youtube.com/watch?v=5RTad9_Ma8c
