Condition notes
I used this for about 4 years at home where it sat in the corner like most NAS do. There are minor scratches on the outside. It has been a rock for me and my family for the past 4 years. Recently, the web management interface became unreachable a couple of times a day and needed a restart. I haven’t diagnosed the cause, so I’m selling it as-is. It may suit a buyer who wants to reset or reinstall the OS, or use it for parts. The unit has been factory reset and all data wiped. There are no disks

No returns. Please ask any questions before buying.
