Check out Samsungs. I have 6 stacked 3x3 and with a simple black, thin edge and tiny buttons, it works perfectly in a multi setup.
On the 712N's that I have, the edge literally measures at .75" Not only is that smaller, but their Samsung logo is a dark grey (so it blends in nicely) and the buttons you use to adjust the settings are hidden extremely well. Point being that they all just flow together nicely with as little break up as possible.
nitro, why not just take the screens out of the cases so u have no bezel and weld your own stand to hold them all together.
I think someone could make a lot of money offering bezel-less monitors. http://www.9xmedia.com/ comes close, I think.
