For a rebuild, you generally want to have enough free space to cover your largest index and then add some for breathing room.
If you decide to do a reorg instead - the space requirement is less.
In this case for a rebuild we would be looking at needing at least 240GB free to store a copy of the index as it is rebuilt. Then you also need log space to support the actual operation.
