I see some mentions of how to remove the bezel here:http://hardforum.com/showthread.php?t=1464591&page=50
However, I think they're probably right about it voiding your warranty. Also, I'm not sure it's safe to run a monitor with the bezel removed - normally the bezel is only removed when repairing a monitor.
As far as mounting them, I suggest using the original stands, which already have height adjustment so you can make sure they line up. I don't know if anybody makes a single stand that can support three 27-inch monitors.
