To me, it looked like the plastic molding was oversized for the circuitry inside, which makes me think there may be variants of these fans. This was the `NOP` variant while perhaps others have `malware drop`, `GPS beacon`, `audio capture` or some other capabilities added inside the same chassis with maximum ease. Of course all of this is entirely speculative. Maybe this design was cheaper to produce or simply shown to be sturdier compared to a smaller alternative. It could even be that they had an earlier circuitry design that was slightly larger and then they realized it could be simplified but at that point that had ordered the chassis.
