I turn off power to computer, then disconnect the PSU. Lay the case on a wooden table. I stand on top of the unpainted part or the case's side panel on top of a wooden surface. Is this correct?
My PSU doesn't have a rocker switch to turn it off with so i'm not going to do that touch the side of it thing.
So I take it that I can do whatever I've been doing eh?
?

Doesn't matter if you are standing on steel, in a pool of water, or on you head.
Doesn't matter if the computer is on steel, or wood table (but not in a pool of water)
You do not need a wrist strap or a mat
Walk up to the computer and touch it. (It doesn't need to be plugged in)
While touching the case pick up the memory, CPU or whatever and install it
ESD is an interesting topic but it can't be explained in a few words.
We build computers. We have six work stations
We don't own a wrist strap in the shop (actually I think we do we just can't find them)

Free Gaza is not right. When you touched it you are not GROUNDED but your electostatic potential is zero (or equal) to that which you touch, in this case the computer

Well the correct way to do it would be buying an antistatic mat and wristband.
You don't need to put it on wood. Just unplug the PSU wire, remove the side cover then touch bare unpainted metal on the case. You're now grounded.

If you are worried about static charge in you the standing on wood etc will not be grounding you. touching the case if the mains supply is removed that also is not earthed
/ grounded. to discharge yourself you have to touch something that is grounded ie heating radiator.unpainted. If you leave the mains plug in that will ground the case but will still supply +5 to a section of motherboard unless the wall socket is switched off
