I've removed a few ISA and PCI slots using a hot-air gun.
My success rate for ISA was quite good but PCI was less good:
I did salvage a few but most of the time part of the socket
also melted and one or more connectors moved.

I was doing this "just because I could" (I was scrounging 
other bits at the time) so I don't know whether the 
salvaged ISA or PCI slots would have worked again.

A blow-torch seems even more destructive than a hot air gun!
