David, I've used an ATI case and it's a very nice piece. Only problem was that it did't come with any instructions on where to drill for a pro tree brake. I called ATI and they said it was just like a stock case. Unfortunately, while in theory it is, the rear of the case has none of the familiar landmarks, like the horseshoe shaped cutout etc. I didn't have to stare at it for long to figure it out, but some specific instructions would have been nice....
