I just picked up a 200 dd as part of my system. I know for a fact that the back is tempered because i can see the stamp on it but i plan on drilling the short side if possible. If not ill settle for the bottom. I tore out the stock overflows because i plan on having 2600 gph running through it and plumbed into my basement with 530 total water volume. I plan on setting it up peninsula style and drill the short side for two 1 1/4 drains in. My next option is drill the new holes in the bottom and have 2 overflows in the middle. I prefer the first because i dont want to loose alot of floor space.
