Little Italy here, and I've found stuff like a IIfx and a DEC server, even a Pentium III a couple of years back. Usually though, I haul back PCs for whatever parts are left in them. This year has been a bit more scant than usual though.

As for cutting the cables, I've never seen that. I've seen CRTs with the yoke snapped off lately, which is disgusting since it's pretty much people (vagrants) saying that they will take the good stuff but let someone else deal with the toxic waste.
