Here we have a perfectly working D-Link DNS-320 NAS. Currently about £52 on Amazon. Yours for only £35.
It's been used, but it's in perfectly good order and comes boxed.
No hard drives are included (obviously at this price), but simply plug in your own SATA hard drives, and within 5 minutes you'll be up and running!
Some really good features on this NAS, not to mention the community support and development with the fonz funplug / debian
A real good quality NAS. Price includes delivery.
Will be able to post this by Saturday, as still need to retrieve my data from the hard drives before sale.
Shipping included in price.
