So that you dont zap your components with static electricity.

If you're asking where to use it, I haven't seen a case with one but I'd think it goes through one of the screw holes connecting mobo to the case. Under the motherboard.

You do not need to use it, but if you do make certain that you use it correctly.

HDDs and Mobos can be grounded via the standard mounting holes and the screws that secure the hardware to the chassis of the case (standoff / HDD rack).

It's the user which is the problem not motherboard or any component.

HDDs would be actually harder to destroy by ESD thanks to their metal casing unless you touch PCB directly... and in that case HDD being grounded doesn't help because high voltage would discharge through low voltage components.
That's why you should always touch metal structure of case before jamming fingers into components.
By the book way would be keeping also case on grounded antistatic surface, but I've myself used only wrist strap and touch case most of the time with other hand to prevent buildup of potential difference between case and myself or always touch case first myself instead of touching case/components already in it with component being installed.

Well said.

I don't work with metal caes that much any more, but when I did I was not much of a wrist strap user (lol - I would forget and move.....)

I generally made contact with the chassis with my hand, or gently rested my forearm(s) on the chassis to ground myself.

What do you think a grounding wire does?

Nothing in normal cases unless motherboard standoffs are plastic or somehow insulated...
I guess they have surplus of pieces of wire and use this method for getting rid of those.

Acrylic cases would be situation in which it would good to have grounding wire going to attaching screws of every (at least sensitive) component.

You don't need it. Hell, even antistatic wrists are pointless. I've never used any - and I've yet to kill any component from static electricity (yes, I do work on carpets too!)
