QNAP NAS TS-431P. I have cleaned it simply with an air duster. There are no scratches, but some discoloration due to aging is visible, so I've marked it as "Slightly scratched or dirty." It was working normally until 2025/12/23, and then stopped. I am selling it because I have completely migrated to a successor model. HDDs are not included. * I am also selling a 2-bay model from the same period separately, so please take a look if you are interested. - Brand: QNAP - Model Name: TS-431P - Storage Type: Network Attached Storage (NAS) - Number of HDD Slots: 4 slots [Included Items] Original box, cushioning material inside the box, power supply, HDD screws, two LAN cables (unused), instruction manual. I believe everything is included. [Shipping Method] I plan to ship it by wrapping the outer box shown in the photo with a plastic bag to attach the shipping label.
