My suggestion is to make disk space size for computers, turtles and disks configurable with NBT data!
It would make server video displays creation easier (so you could store big files by increasing limits for specific computers)
It would also allow server owners to add crafts to increase computer disk space. (For example, computer + music disk => computer with extra 256KB of disk space!)

The integration can be absolutely seamless with just making computer_space_limit configure default computer space limit and etc.
