Quick take
A network attached storage (NAS) box gives you one place to back up computers, serve files to the rest of the house, and keep a private cloud without monthly cloud fees. The real decision begins with a fork: do you want a unit with a drive already inside, or are you ready to install your own disks? From there, the condition, the bay layout, and the listed price do the narrowing. These four options are listed from $249.99 to $374.99, so the spread is meaningful but not enormous. The LinkStation 210 is the preloaded route, the white enclosure is a bring-your-own-drives home cloud, the Qnap TS-451U is a used server-style unit, and the Synology DS423 is a new enclosure for people building their own storage.

Product notes
2TB Network Attached Storage - LinkStation 210 for Safe File Backup and Sharing
The clearest reason to look at this one is the included 2TB drive, which makes it the only true "storage out of the box" listing in this group. The description describes a centralized backup hub for all your devices, scheduled backups, and SSL-encrypted file sharing, so it can handle day-to-day file protection without a separate cloud plan. It is also listed as new and supports desktop and laptop clients. The limit is expansion: you are working with the built-in drive rather than a multi-bay enclosure where you can slot in extra disks later. If your photo and video collection is already pushing past 2TB, this preloaded route will be tight.
2-Bay Network Attached Storage NAS Enclosure Diskless White Home Cloud Backup
This white enclosure is for people who already have drives and want a quiet, tabletop device for a private home cloud. The listing describes 24/7 monitoring with IP cameras, access from desktop, laptop, or mobile, and a low-power plastic-and-tempered-glass build. It is marked new, and the Android compatibility is explicit, which is useful if you manage files from an Android phone. The obvious limitation is that it ships without drives, so you need to provide your own storage before the enclosure can hold anything. It is also a compact option compared with the larger enclosures here, so it works best for modest storage needs and a smaller footprint.
Qnap TS-451U 4-LFF J1800 2.41GHz CPU 1GB RAM No HDD Network Attached Storage NAS
This used Qnap is the only listing in the group that reads as a server-type unit, and the title spells out the core specs: a 2.41GHz J1800 CPU, 1GB RAM, and large-form-factor drive bays. If you are comfortable buying drives separately and want a used chassis at a lower entry point, this is the only server-style option here, and it gives you a different hardware philosophy than the home-oriented enclosures. The trade-offs are clear from the listing: it is used, and it ships with no HDD. You will need to source drives on your own, and the used condition means you should go in expecting a pre-owned component rather than a sealed new product.
Synology DS423 4-Bay Network Attached Storage Enclosure, NEW, SEALED, DISOUNTED
This Synology is the new multi-drive option in the lineup, with 2.5 and 3.5-inch drive support, 2GB of DDR4 RAM, two gigabit Ethernet ports, and a pair of USB-A 3.0 ports mentioned in the description. That combination makes it a practical foundation for a home office or a small team that wants room to grow without buying a huge chassis. It is listed as new and sealed, so there is no question about wear. The catch is that it is diskless: the enclosure itself is the investment, and the final capacity depends entirely on the hard drives you add. If you are looking for a turnkey NAS with storage included, this will not be that.
Final recommendation by use case
If you want to unbox one device and start backing up immediately, the LinkStation 210 is the most direct fit because the hard drive is already inside. If you already have drives and want a small, quiet enclosure for a home cloud, the white 2-Bay Enclosure is the simpler match. If you want a used server-style unit and are comfortable sourcing your own drives, the Qnap TS-451U is the most direct path to that configuration at a lower listed price. If you want a new enclosure with modern RAM and dual gigabit Ethernet, the Synology DS423 is the one to build your storage around.
