Well it all depends on what you're after as far as an overflow.
You CAN indeed have it all internal and drilled and plumbed from the bottom. But for me, those overflow designs take up way too much tank real estate. I prefer a small internal overflow and the rest just plumbed through the back. More room for aquascaping and corals
Here's another very small footprint overflow that I was looking at also.
