Sleeving isn't fun.. lol.. My roommate bought his molex extractor from frozencpu.com. For the three pin or the floppy plugs just use a small screw driver and push the clip things out.. Make sure you bend them back though. Also it took me about an hour to do the ATX cable.. If you want to see how it turned out check out the pics at :
one more thing.. once you have the molex plugs off wrap the wire connectors with scotch tape. It has a low friction and will stop the sleeves from grabbing on the edges. Good luck..
