It's best to keep the dialogue on the forum and not pm me as otherwise people lose the way the thread is going and it may be that others have the same problem as you. If you want to post your pm here we can then try and come to some conclusions.
All the best

ok. Well i got the cm 690 adv 2.

On newegg some ppl say the thing has black interior painted. Would that cause ground issue?

The "black interior painted" should not be an issue since the motherboard and the PSU are tightened to the case with metallic screws I assume. I'm not sure if the following will help. If you've ferrite core (e.g. something shown in the figure below), you may clamp the speaker wire with the ferrite core. If you note the monitor cable, it always has a "bump" (which is a ferrite core). However, if we can "hear" the noise from the speaker, then the frequency of noise should be somewhere between 20Hz ~ 20kHz I guess.

On my speaker audio there's a bump that looks like the ferrite core..

Your drive and PSU should be grounded as you say by the screws(in theory at least) but if your mains cable has a faulty earth connection or even the socket that you plug it into it will have the same effect.

The thing about the interior painted panel is some ppl say that paint might cause ground issues, cos the metal screw doesn't touch the actual case..

I thinkl that if you put a meter between the case and drive you would find that they connect. I agree that the painted surface isn't ideal and you could always remove some of the paint behind at least one of the screws that way you would make sure it is at the same potential(connected).

After doing some digging it seems to be the opinion that it is down to onboard sound chips that are of a lower quality than a discrete sound card. I suppose it picks up frequencies from the motherboard etc. Anyway try a seperate sound card if you can and let us know the outcome.

I just did a test with the multimeter and touching the standoff screw and case at another screwhole point (that's empty) produce a beep (which means there is a connection)

That's good, at least that eliminates the lack of continuity of the ground possiblity.

How do you intend to proceed from here?
