Actually not an electrician, but an EE. There is a difference - in that
you wouldn't want me to try and wire up a house!! (I don't know the
electrical codes, and haven't done that stuff; that's for the licensed
electricians)

And that's 120 VAC!!
In the power supply's output, we're just dealing with 3.3V, 5V and 12V.

Yeah.
I never have been able to replace a light switch with the power on w/o
getting some shock at some point (I was too lazy to find which ckt breaker
turned it off, so I thought I'd take a "shortcut" - never works well for me)

LOL. Actually, I'm taking on the other one (the case fan) now!
Once (IF) that one gets done, I'll "reconsider" the power supply and its
fan, but with a bit more "diligence". This time, I want to see my Dell
model number in there!
