I agree . . . it is the second time . . :-)

Even on standalone solution like my RepulseGold card, i had some little noise related problem, when the card WAS installed in the original A4000D case.

I had fixed the problem, isolating physically the rear RepulseGold bracket from the case. (due probably to a ground loop).

No problem when i've changed to the PowerTower case.

Audio, is very hard to handle, from a hardware planning POV.
