Notched tank top and external box. Takes up no tank space and the tank doesn't have to be drilled anywhere.
Do you mean the siphon type overflows?Notched tank top and external box. Takes up no tank space and the tank doesn't have to be drilled anywhere.

That's really cool, I've never seen those beforeNo, those are the worst. I mean where where the top edge of the back of the tank is cut a bit lower, and it overflows into an external box where your drain pipes are. People refer to long ones as "coast-to-coast" overflow.
Here's a nice write up, although I would have made his box a bit deeper: http://www.glassreef.com/basics_overflow.php
