In that case, you'd probably also want to bet that we all wear short
sleeves at all times when working on a pc, and I personally don't
always do that. All the machines I have here are towers, and I don't
want to go through the hassle of fully unplugging them just to work in
them, so I work with the tower cases standing like they normally
would, which means my elbows are usually on the ground. Even if
working on a desktop, most of the time, I work on those with the
machine facing me, like it normally does, which means that even if you
do lean an arm on the chassis, usually the bulk of your arm is
actually in contact with the plastic on the front of the chassis, and
not with the metal frame. You also want to be in contact with an
unpainted metal part of the chassis, (the best place is usually the
outside of the power supply at the back of the chassis), since painted
metal surfaces don't do the job.

Personally, if I'm doing something quick and dirty, such as swapping
cards in and out, I'll touch the back of the case with 1 hand, while
working with the other. If I'm doing anything major though, especially
if I need both hands inside, I do use a wrist strap. After all, it
takes very little static electricity (which you might not even feel),
to destroy 1 or more components.
