08 Now that I've opened my Mac how might I electrocute myself? (Macintosh hardware)

Like most computers a Macintosh contains lots of exciting high voltage
equipment that can deliver shocks ranging from mildly surprising to
motherboard-frying to lethal. Since compact Macs cram the high
voltage picture tube and power supply into the same cramped space
shared with the motherboard, they're particularly dangerous. If
you're intent on committing computer-assisted suicide, here are a few
simple procedures that will greatly enhance your chance of success:

* Be sure the computer and all cables are plugged in when you
work on it. It's difficult (though not impossible) to get a good,
solid shock without at least 120 volts of AC surging through the
works.

* Wear lots of metal jewelry. Long, dangling gold bracelets make
the most effective unexpected electrical contact between the picture
tube and your heart.

* Naturally you yourself want to be nice and clean before working
on your Mac so take a long shower. Don't bother to dry off though.
The heat from your Mac should dry you just fine.

* Pay special attention to the picture tube and flyback
transformer. Fondle them. Know them. Love them. If you're still
conscious take apart the power supply. (That's the silver box with
the big red warning letters on it.)

* Invite all your pets and small children to watch you work.
However there's no reason to invite an adult who might have the
presence of mind to call 911 should you be injured.
