If you carefully change 2 fans in the ASIC and clean it from dust, it will be difficult to find that the ASIC was used before.
Now there are a lot of large farms in China, so mining equipment is also sold on trading floors.
I am sure that in the near future there will be a lot of interesting proposals.
I think you've heard about the new Litecoin / Dogecoin L7 ASIC.
