Building a new tank need opinions

[Dez]

I just built a 46 gallon glass tank with center overflow, however, it's on the inside. How were you thinking of putting it on the outside? Would you notch into the glass? What about just a hole drilled in the back wall and a 90 elbow as your overflow. We do a lot of client's tanks like this and it takes up minimal room...

One halide should be sufficient, it would be awesome actually.
