If my tank has no holes, is it a hassle to drill it or should I just go with an overflow box with a "custom" drilled nozzle hole to prevent backflow if power goes out?

This is basically my biggest dilemma. I don't want to come home to a flooded basement, and I want the better skimming strategy of the two.

Please help me out.

I'm doing A 90 Gallon tank right now and am lucky enough to have a friend with glass hole saws to do the holes for me. I would go with drilling vs an overflow box, had one on another tank and found them very noisy. Try a Local glass shop some have a mobile service.
