To drill or not to drill?

[duncangweller]

You can always drill a hole in the back pane of glass towards the bottom if the bottom of the tank is tempered as mentioned earlier

It is definitely not tempered as the return is drilled through the bottom. Is there any major advantages having the tank drilled on the bottom versus it being on the side. I am really only concerned about the bottom pane having pressure from the water on one side and none on the side I was drilling.
Thanks.
