don't know the exact dimensions., i just had one in my hands in berlin MUM.
it is at least as deep as the ccr1072 and very heavy. heavier than the 1072.
i wasn't able to find a photo of it, just one of its non-poe counterpart, just to get an impression - it is maybe additional 10-12cm longer.
as i remember it has fans on the back, so i would not install it into a shallow cabinet anyway.
