There are so many great ideas if you are looking to repurpose it. On pinterest I have seen them turned into office desks and even drinks cabinets.
It depends on what kind of organ it is. Old pump organs generally have fancy cases, and may have value to a musician or an instrument restorer who wants that particular sound! More modern (50’s-80’s) home organs have more sleek wooden cases and can be repurposed into desks (especially if they have a roll top), bars, or entertainment centers. The speaker cases can be repurposed, too. Be creative!
This is my favorite:
