Electrolytic cap "protection"

The caps leaking electrolyte wasn't as much of an issue as the shorting
of the caps and causing other problems. At the best it was random
reboots, at the worse it was total destruction of the VR section of the
motherboard releasing much magic smoke and propelling pieces of the
regulators all over the case interior. Not to mention toasting the cpu
and memory simms.

We never attempt to repair them, just replace them. When a replacemnt
motherboard only costs $45-60, the tech time cost is higher than scrap
snd replace.
