I have a 540, it's 30 inches tall. I went with that because, like woefulrelic said, it fit through the door--just barely. I wouldn't go any taller than that because it's the deepest tank that I can reach the bottom. So I can stick my arm in and touch the bottom if I'm standing on a step ladder. That's a HUGE deal.
I wouldn't do a glass tank, but this is hotly debated here. I feel like acrylic is less likely to bust. It's also much lighter. The only problem I have with acrylic is you can't keep big cool pleco's in an acrylic tank. You can buff scratches out of acrylic tanks, but you won't be able to keep up with a big Royal Pleco rasping all over it at night. I hear stingrays tear up acrylic, too.
Check out my build thread, and my "540 -- mostly vieja" threads. Video's of the tank and the fish in it. If you know you want to keep fish, acrylic is awesome. If you want rays or pleco's, then you might have to get glass. Just do some research if you're gonna get a big glass tank--it's gotta be done right.
