The link you gave, Operandi, lacks the contacts. Be sure to get both shell and contacts. jab-tech.com and svc.com both have the shells and contacts in several colors. A special crimp tool works best but it's only worth the cost if you do a lot of connector crimping. jab-tech used to carry those as well - IDK whether SVC has 'em or not.. Last I looked, jab was OOS (back in stock - just checked) - theirs is the one I use. If it is still the red handled one like I have, then the die set that comes with it can handle most open-barrel contacts like the fan connectors, "Molex" drive power, etc., and other die sets are available for it, but jab doesn't seem to carry them. I have seen them elsewhere - I think maybe at Jameco or someplace like that. Crimp AND solder works best but few are willing to take the time to do that...
