Ease of cleaning... If you only plan to do this to one or two small tanks then doing it to the top would be fine. If you're doing it to a 29 gal or above, think about the hassle of reaching down into such a deep enclosure trying to get stuff out, trying to remove bedding, wipe the bottom, etc.. What a pain. Especially if the tank is sitting on a shelf or table which is more than a few feet above floor level.
