Lightly used, but in very good condition.  Comes with a 40GB hard drive, which is a little noisy, so you might want to replace it.  I had the system format and error check the drive and it reports no errors.  I did not enable the wireless, so you will be able to once you receive the unit.  I will include a CD with installation guide and user manual.  It has 10/100/1000M Ethernet.  Works flawlessly and will be missed.  I was using this with OSMC media server for media storage.  Please review all pictures and read the description, ask all questions prior to committing to bid or purchasing this item.  As with all electronics, they are sold "as is" without warranty or support.  If it is not shown in the pictures or listed in the above description, then it is not included.  Not sure, just ask.

D-Link's DSM-G600 gives you the option to make your network storage wireless. It supports 802.11b/g and WPA/WPA-PSK security. If you want to go wired there is a Gigabit Ethernet port on the back.

The enclosure supports IDE drives. This gives you a chance to use a spare from a previous system upgrade, or go big with a 750GB drive. If even that isn't enough capacity there are 2 USB 2.0 ports that you can attach more drives to.

The DSM-600 is more than a storage device. It has a built in UPnP AV server to stream media to the various computers on your network. You can also use it as an access point to create or supplement a wireless network. Just run the RJ45 cable back to your router and you're all set.
