Never EVER EVER will I do HOB again. Regardless if its Fresh/Salt water. What's the point.. and why bother with stupid HOB garbage.
Drill it, If your drilling the back I would go for an external overflow otherwise why not just drill the bottom makes no sense.
If you drill the bottom go with a Herbie, by far the most fail proof silent overflow I have ever ran. (I've ran them all except bean animal which doesn't even make sense to me to begin with)
If you're drilling 2 holes and drilling the bottom for internal overflow I would take the extra 3''-4'' and drill 3 for a return. It beats having to run the return over the back. If you're going to run the return over the back anyways.. WHY Not just go with an external overflow?
