I personally would use a standard heat gun to remove soldered parts for salvage. Just gun and pull. A smaller air nozzle helps.
Once again thanks for your comments.
@feilox: I can shoot a pic later the day if you like. I'm sure you know these 3-pin fan connectors. I have some spare fans lying around that I sometimes use with batteries for cooling... well, anything you can think of.
The battery holder is a pcb-mounted holder for a CR2032 button cell, I'm sure I can use something like that for a project some day.
