16" cube ideas

With an external overflow (with the glass notched out) you don't tank up any room within your tank. Therefore you have the full inside dimensions of the tank to work with for aquascaping. IMO it is a much cleaner look having only a little notched area in the back glass vs a partition in one of the corners.

Okay i can argee with that! ok so if i go with the external overflow, i dont have to get my tank drilled? just notched right?
cutting the notch in, it this a difficult thing that i should take to the glass shop to get done, or can i do this with a glass cutter?

Building an overflow, this is somthing that i keep trying to research, but can find any real good plans out there, i have seen tonnes of examples but nothing really explaining on how to do it

this tank will be viewable from 3 angles most likly

sry for all the questons , i just wanna try to do this right
