Soldering Iron + Solder Wick. If you are skilled (which I am guessing not, since you are asking for advice) You can heat both leads a the same time and simply pull the Cap up. Reverse to install. New caps come with long leads so you can 'Shimmy' it in. I would leave this to someone who knows what they are doing if I were in your shoes, or you may end up damaging a Solder Eye which is a pain in the ass in itself to replace, much more to blabber on about how this is a bad Idea, I would just save yourself a headache and take it to a computer repair shop with new Cap in hand and ask how much to replace. good Luck!
