Question Where do I connect ground wire from power connector? (safely)

[ThomasBuilds]

As it says in the header, I don't know where to connect the ground wire from the power connector, C6 btw

If it matters to anyone I'm building a mini pc for my dad and not accidentally killing him is of my higher priorities with this particular project.

I was probably going to connect to the ground wire to the case by using it like a washer for a case screw.

If I'm about to do something horrendously stupid please lmk, thank you

Yes, you ground to the case.
