This system serves my as NAT Router to separate my network from the LAN in the building I am living. I bought it 3-4 years ago and it was really worth its price and by the way, energy consumption is really low (< 15 Watt). This system runs a Ubuntu 10.04 LTS server version and on this system I set up a Dropbox to have access to my account there too.

These sources were helpfull during my approach:

and basically this post is a mixture of both of them 😉
