It has been a long time since I opened one of these, but at the time I remember thinking it must be possible to open one of these without deforming it. Like anything correct technique must be the key. Companies like Wenzel do this on a daily basis and I would guess their technique would include a hotplate or hot air reflow. I think it is possible open with minimal deforming of the metal case even with a regular solder station by wicking one side and and sliding paper or other thin material to keep the solder from re-tacking when you heat the next side.
