Synology DS411j DiskStation 4-Bay NAS in 100% working condition. This NAS features four drive bays compatible with 2.5in and 3.5in SATA drives, gigabit ethernet and two USB ports, making it ideal for use as a local backup server. I have factory reset the NAS.  

Note there is some slight yellowing on the white housing.
