I was once able to fix a failing motherboard by cutting out the "bulging top" capacitors and soldering new ones of the same spec on the parts of their legs that remained on the board. That was after almost ruining it by attempting to actually unsolder the original caps from the board. Those things are soldered hard! I tried to apply too much force, slipped, and made a big scratch on the board with the soldering iron. Didn't go through the varnish though.
