An overflow is used to take water from your display tank and send it to a sump. An overflow can be either drilled, or a hob overflow box. A drilled overflow is safer because you do not have to worry about the syphon breaking like you do for a hob overflow. But if you do not plan on having a sump then there shouldn't be any reason to drill your aquarium. Hope this answers your question.

If you opt for the HOB type I would recommend make it yourself from PVC. A PVC HOB will cost you about $15 max while a store bought HOB will cost about $40-$80 depending on the size of your tank. I have a PVC HOB on my sons 55g and it has never lost syphon when power has gone out, an it takes up way less room behind the tank than a store bought box type HOB. Just my opinion though...
