A daycare in my city has taken a donation of desktop and laptop computers for the older children to take apart.
I am concerned that the various capacitors would present a shock hazard for the children, and have volunteered to discharge them.
The original plan was to unplug the computer, hold the power button to discharge the PSU output capacitors, then cut off an ATX cable and short the rails to ground, which should take care of the electrolytic filter capacitors on the motherboard.
Would this create a floating potential that could cause a shock if someone were to be touching the case and something else that was properly grounded?
Also, would there be a good way to discharge the PSU input capacitors?
