ESD protection with wrist strap on a painted case

[duftutta]

I am planning on starting my first PC build very soon, however one thing that has left me confused is the subject of ESD. I own an anti-static wrist strap, and I know that it is recommended to attach the strap to the case. However, both the PSU and the case I am buying are painted and have no bare metal on the inside.

Where should I attach my wrist strap in order to be grounded? What should I do as far as setting up the PSU to be grounded?

Any other suggestions are also welcome, and thanks in advance.

(Question previously asked on /r/buildapc, however I was not told there how to use a wrist strap so I am asking here instead.)

I've never used a strap , and have built a few dozen computers.

Thanks, but I personally would like to be on the safe side, and would like to know how to use a wrist strap properly in my situation.
