Buffalo,

If you leave the machine plugged in and just turn the switch on the PSU to
OFF,

That might once have been be good advice, but not so much nowerdays.

As he's reminded you in a later post, he did say "on the PSU". I've yet
to encounter a case where that isn't a real switch. (I have, however,
encountered PCs - I suppose I should really say PSUs - where there
_isn't_ a switch on the PSU itself.

Pulling the powercord and waiting for a minute or so (to give the capacitors
in the power supply a chance to drain themselves) is the best way to go.
With, or without actual grounding.

It's a good way to ensure things are discharged, but it actually
_isolates_ the ground. Personally I've not found a case where such
isolation has caused a difference in potential anywhere near big enough
to cause harm, but ...

So, just touch a metal part of the machine before touching any electronic
part and both will be at the same potential.

And that will be true even with power cable (and its grounding) removed. :-)

.... I'd agree with the touch method. (Going the whole hog with a wrist
strap that has a clip for the chassis is even better, but I wouldn't buy
one just for the sake of it. YMMV.)
