The 60" cube rule does provide enough room to store 60 balls. That being said its still a giant storage device and i doubt something that large would ever fill up to its liimit(although I would love to see the match where it does.)

My team's storage area will hold about 20 balls and come up to around the 4 foot mark probably. We're trying to make it work with an opening on the top and there will be one of some kind but the size and shape of it will probably be determined mostly by weight and time. I know that due to its design while it could accept balls quickly, probably not as quickly as you're imagining and for any high speed delivery it would have to be accurately placed.
