A NAS that hosts it's own network and can run on it's own power. It functions as a standalone server capable of hosting websites and bulk data storage without requiring internet connectivity or a reliable power supply.

Inspired by the whole cyberdeck thing. If you have a cyberdeck, surely you need something to jack into?
