## Matsayi
,most Apple Network Servers had been removed from service and most had been returned to Apple or sold on the secondary market, either factory remanufactured or as-is, or sent to a recycler and crushed. It was once not uncommon for a well-featured ANS to barely recover the  minimum bid on eBay. Shipping of an ANS is expensive, about  from a U.S.-to-U.S. location , if sent via bulk shipping.Few, if any, replacement parts are available, particularly not the mechanical components.

,Apple Network Servers are sometimes seen and sold for over  on eBay.
