Old Visio Stencils

I am looking for Visio stencils that must be past their EOL. I have looked on Dell and VisioCafe and can't seem to find the ones I'm looking for. I would prefer not to torrent them, so if someone could email me them or send me a link as to where they are, that would be great. I am looking for PowerEdge 850 and 860, as well as PowerEdge r200, and lastly the OptiPlex 9010.
