Description
I am selling my Synology DS423+ in mint condition. It was purchased from Galaxus in November 2025 and is still covered by the manufacturer's warranty until 24.11.2028. The NAS was used with four WD Red Plus 8TB hard drives, and I never experienced any issues with the system. The only reason for selling it is that I needed to upgraded to a solution with more drive bays. The unit is complete and comes in its original packaging with all the original accessories: 1 × Synology DS423+ main unit 1 × Swiss power cord 1 × AC power adapter 1 × RJ-45 Ethernet LAN cable 1 × Set of screws for 2.5" drives 2 × Hard drive tray keys The NAS is in excellent cosmetic and working condition. Please refer to the attached photos for its exact condition. Thank you for your interest.
