Recently replaced CPU, mobo & PSU due to failure after the power went out during a windstorm.

Now, I'm getting a pesky case rattle/buzz, particularly when the system is hot (e.g., during gaming.) Setting my hand or a couple of books on top of the case cures the noise... momentarily, then it moves to the side panel. Removing the side panel stops the noise altogether, but nothing inside the case would be in contact with that panel.

None of the cables are interfering with the fans, everything is secured properly, GPU fans aren't hitting anything. Ideas?

Thanks a bunch in advance!
