Synology DS508 5-bay NAS with 5x 2TB WD enterprise WD2003FYYS hard drives.
The unit is fully functional (if a little dusty); it's just that I changed my storage strategy a while ago and it's surplus to requirements.
Comes with a UK power lead (though can - I think - supply a continental European one) and a CAT 5e Ethernet cable.
A couple of these (used) with 5x 3TB drives have gone for over £300 on eBay
The drives go for in the region of £30-40 a piece on eBay
If you are interested, please make me an offer; I'm not after a fortune for this...
