I only have the unit, power pack and ethernet cable. The software is downloadable from Synology, and you'll need a couple of HDDs. I've had 1TB's and 500GB's installed previously, but it might go to a larger capacity. The software is easily upgradable which will need doing as it's been off for a while!
£25 good to anyone?
I'll post it if you want at cost, but would prefer collection from here or a nano.
