I wouldn't remove the rim if it had the metal reinforced plastic support in the middle. The fact that it has the glass support would indicate that the rim is more decorative than anything. My only concern is that the glass support in the middle is attached to the plastic. I think if you euro braced it, you would probably be ok... but if you do it, do it at your own risk. It'll probably be ok, but that's purely a guess.
"What, exactly, is the internet? Basically it is a global network exchanging digitized data in such a way that any computer, anywhere, that is equipped with a device called a 'modem', can make a noise like a duck choking on a kazoo." - Dave Barry
