This is the same case and foam cutout that my 5" came in. The cutout measures an extra 4 3/4 inch so I'm guessing that they use the same case and foam cutout for 460's and 500's up to 8 3/8", and the 10 1/2 would probably work as well. The foam insert comes right out, so if you turned it upside down the 10 1/2" would fit nicely and 12 1/2" one should fit in diagonally. It is a big case. 18" X 10" with a 20" diagonal (inside dimensions.)
I just tried to find a picture of one on G.B. for you, but all of the cases on there are just plastic, no foam. (They are getting $45-$50 plus $14 shipping.)
