If it's a PS/2 type keyboard connector (small plug) there is a plastic pin 
that often gets broken off and left in the socket if connectors are pulled 
out violently, blocking a new keyboard being inserted.  (Seen it often with 
mice.)  If this is so, I've had success getting them out by using 'blue 
tack' (a semi-adhesive goo used to hold the kids drawings on the wall) on 
the end of a matchstick to grab hold of it.

Sounds like this machine was lucky, though replace the fan when practical...

Are they completely toast?  Can the hard discs be pulled and tested in 
another machine?  Failing that, companies do exist  that specialise in data 
recovery in these situations.  For a price.  It depends how valuable the 
data is...

Oh... and, as my boss would say, it's an opportunity to sell them a backup
