If the case isn't grounded, you aren't doing any good by touching it.
Some computers recommend they are plugged in for service, others do not.
To be safe, use a ground strap connected to both the computer, and your wrist, that goes to something else that is actually grounded (copper water pipe, case of another plugged in (and grounded) pc, etc)

No. ESD is Electro Static Discharge. The key is that you, any parts used, and the computer are all at the same potential level. You can all be floating at 50,000 volts and all is well. No transfer of energy = all is well.
Now, that said, the surest way to ensure that everything is at the same potential is to set up a grounded ESD workstation, with wrist strap, parts pad, and work surface all grounded together. This is both cost and space expensive, however.

If you don't have an anti-static wrist strap on, you can touch the case or the power supply. The power supply is a better option than the case though.
If it's a quick and easy upgrade, (i.e. memory upgrades), I generally don't bother putting on the wrist strap, and I just touch the power supply.
Just remember to have the computer unplugged. I even turn off the power switch on the power supply. Even though the chances are relatively small for getting shocked, do you really want to explain to the paramedics why you were working with a plugged up computer?

Atheist has a good technical explanation, and that sounds reasonable why my friend's P4 was not zapped when we work on changing its hardware on a carpet and no ESD grounding at all.

Yes,the case or chassis need to be grounded.The case is grounded when the power cord remained plugged to the wall outlet.However when you work with the computer, the power of the wall outlet has to be turned off to ensure your safety.

Yes it will need to be grounded.
( I never disconnect from mains to be honist.. However if your not sure what your doing be very careful. )
chances of getting a shock is TINY as its only a max of 12v with very little amps.

You only have to ground yourself to the tower. The tower itself can be hanging as far as it matters.
