Anyone ever added extra power to printrboard?

Has anyone ever soldered additional 12V power wires to a printrboard to provide extra power for running a QU-BD heater? Just wondering if there are known good places it is convenient to add power. I've been looking at the eagle files, but I'm not sure I can tell what I'll really need to do from them. Working examples would help :-).

I'll probably solder suck all the extra holes and add the missing headers as well once I go to all the trouble to start modifying the board.

Of course, when I destroy the board, that will be a good excuse to upgrade to a Rambo or Ramps or something :-).
