The Unabomber’s cabin is kept in an FBI storage facility, and Richard Barnes took some pictures of it.

Also, do you know why we call him the Unabomber? From his wiki: “Before Kaczynski’s identity was known, the FBI used the handle “UNABOM” (“UNiversity and Airline BOMber”) to refer to his case, which resulted in the media calling him the Unabomber.”
