On the hard drive note - it is much more fun to take them apart and use the
storage (platter) for a conversation piece (shiny coaster) and the two
magnets are much stronger than you can find else ware. Also they are fun to
play with until you pinch a finger or hand.

My rant / experiences
CRTs have a lot of lead in the glass to protect you from low energy
X-Rays that are a natural result of stopping a fast moving electron. The
lead is fairly inert in the glass but can become a problem if in a
situtation where it can leach out. In time the LCD technology will put
an end to the lead glass CRT problem.
Printed circut boards have far more lead that is available to cause
problems but don't get me started on the no lead solder for electronics.
There is no logic in using tin/silver/copper no lead solder to remove
lead in cosumer products when the failure rate of no lead solder is 5 to
10 times to cause a failure in the product.
Ever wonder why file servers, pace makers, communications systems,
medical instrauments etc are not required to use no lead solder?? Of
course the French are using no lead solder in the Airbus 380.
Most CRT monitor/TV high voltage power supplies do have plenty of
voltage to bite you good but the current available is not going to weld
a screwdriver to them. There are powersupplies that do have lower
voltage but higher current designs that very well will either weld the
screw driver to it or simply vaporize an inch or two of the blade. Have
had that happen more than once. Some products I used to service were
equiped with Thunder Sticks to safe the power supplies.
Been there, designed them, worked on them, watched a few fail and
explode. Never took one to the body and I don't pland to start now.
Of all the things I would worry most about during the disposal of an old
computer is the hard drive(s). You just do not know what is stored there
in the way of personal data. Ever made an internet purchase with your
credit card? That info may still be there in a deleted file just waiting
for someone with idle time on their hands.
Best to remove the hard drive and destroy it with a good sized hammer( a
44 Mag also works well) or find some software that does a DOD full erase
by writing various bit patterns over the whole drive several times. Do
not just format the drive or delete the partition as that still leaves
everything on the drive in readable form with some simple software.
