This is a NETGEAR ReadyNAS RN104. Includes the main unit, HDD trays, AC adapter, and box. HDD is not included. I have confirmed normal operation before listing. It has been initialized (factory reset) and lightly cleaned. Firmware is 6.10.10. I plan to wrap the outer box in packing material for shipping. Returns are not accepted to prevent swapping. No claims, no returns, please.
