The Nokia phone is just to give some scale.

The box on the right is the Linux server - it's sold as a NAS storage device (Linksys NSLU2) that all you need to do is attach a USB disk and away you go. But, there is an active community out there who have figured out how to load a full Linux distribution onto it, checkout http://www.nslu2-linux.org/wiki/Main/HomePage . This is all I have done, and then configured a few services so I can use it as an install server for Solaris.

The box in the middle is just a USB attached disk.

(Behind the phone can be seen another NSLU2 being used for it's intended purpose)
