Magnetic Shielding
Beretta:
most likely the subwoofer is not shielded so you'll need to shield the monitor.. a piece of sheet metal (thicker the better) between the subwoofer and the monitor will eliminate it.

Make sure you use a ferrous metal, as copper or aluminum won't do anything to block the magnetic interference.

Since there was a lot of time today I opened up the machine today. The subwoofer made no difference if it was on or off, so it is not coming from the transformer in the housing (as you guys said it could be from the magnet). The speakers up top are tiny things (3 inch ovals with no visible magnets). I moved the smart strip out of the cab and put it on the floor outside the cab about a foot away from it on the floor, still had the shake. The Linksys USB network adapter had no effect on the shake as well. The marquee light was unplugged as well so there is not EMI from it. So at this point it seems that I will need to just hook up the monitor to my laptop (with the main PC off) and see if I continue to get the shake. If so I will pull out the subwoofer and the speakers to see if it goes away. Worse case is that I pick up a shielded woofer or use an ferrous based metal sheet metal like you guys suggest. I'll let you know what I find, thanks!

It has something to do with the monitor itself. I took everything out, including the tower. The tower was about 4 feet away from the monitor thanks to a nice VGA cord and still it still has the shake.
Maybe it is time to contact Billabs and ArcadeVGA on this. Thanks gang, it is not a magnetic shielding issue.
