Its alive!
All up and running last night. Powered by the router using a super short micro USB cable, nice and minimal. I'm going to find a way to mount it to the back of the router so its secured as for now it just resting behind it.
Connecting remotely via VNC.
Only thing I need to do now it work out how to make DSLStats start automatically on boot.
Reading back I see you guys use a bash script. As a complete Linux noob, anyone mind giving me an idiots guide how to do this please?
Thanks for all the help thus far, it was as I suspected far easier than I thought.
