These cabinets are built of HEAVY gauge steel, with a lot of 
heavy steel framework inside.  They intentionally built them 
heavy to withstand rough shipping.  The cabinets should 
separate fairly easily, just mark the locations where cables 
plug into backplanes, etc.  Tape up all dangling cables.  My 
guess is that the individual cabinets won't be all that 
heavy, a couple beefy guys should be able to work it down 
the stairs safely, but it will be a rough, sweaty job.

Yes, if this has a 50 Hz linear supply, the power supply 
WILL be very heavy.  It may be possible to remove the power 
transformer to lighten that cabinet.
