I posted before stating that I had a large glow coming from the bottom right of my screen. So I sent my new Imac back to Apple for them to investigate. They sent me another iMac that was BTO that came back with the same issue. Well they just had a chance to look at my first iMac. What they said is that the screen was screwed in too tight and the issue can be fixed by having someone in store at the Genius bar to loosen the display so it is only lightly tightened. I guess this is fantastic news for myself and others. I am taking my iMac in tonight to have them adjust it. They must have some heavy handed people in the factory. Hopefully I can post some before and after pictures later tonight!
