Some of the damage will be things dead.
Sheesh, the MTV generation strikes again. There are several
things which come to mind, that will fail sooner with
time. One is the power supply. Since PC power
supplies are switching supplies, the secondary
regulators may have kept the higher voltages off of
the motherboards. Unfortunately, the electrolytic
capacitors within the power supplies are probably
stressed a little, depending on the supplies, as
some will shut down to protect themselves (if this is the
case, everything is fine). Otherwise, some of
the electrolytics may have produced a gas within the
capacitors and popped the seals. Many of todays
electrolytics have a thinner area on their seal (on the
bottom, looks like a dimple, usually there are two of them).
This failure can be detected with nothing more than your
nose. It is a very distinctive smell. Turn the PC off
for a bit, and just sniff the rear fan area. If the seal
was weakened, over time you will see random crashes, reboots,
corrupted hard drives, and the like, as the electrolytics
dry out and the voltage ripple increases. You can always
use an oscilloscope and look at the voltages comming from
the case power supply.
Some of the power supplies are made better these days, and
if it has the proper circuitry inside to protect itself,
you don't have anything to worry about. If you find a few
blown boards, CPUs, RAM, and such, it would probably be a
good idea to change out the case power supply at the same
time, as you don't have one of the better supplies.
Hey, a word of advice. Take some epoxy, liquid nails, or simular
material and fill the hole where the little red slide switch is.
Oh, and if any moron wants to flame me, flipping that switch
does not cause the output voltages to automatically double.
