Provided one has the equipment...

Not everyone is an electrical engineer and they don't warn for
nothing to be careful with PSUs, which can still contain lethal
electrical charges (also after having been fully unplugged and
seemingly discharged).

Perhaps, but plenty of others systems weren't but still run fine.

Unfortunate, the DS10 for the rest is a very nice system.  But
maybe these are a few unlucky cases, too.
