CrunchBang Linux

So here is the situation. I have a limited experience with Linux in the past (mostly CentOS and Ubuntu) however I do have several experienced Debian users avaliable at work and home to pick brains from.

Here is the system: Its an ageing Dell Inspiron on an amd64 architecture and a G of RAM.

Here is the use. I need a lightweight OS that I can use to host a small fileshare for me and a handful of friends (no more than 5/6) and a Teamspeak3 server for the same. I could easily use the WinXP that is currently on the system but I want something more lightweight, prettier, and I am aching to get more experiance with linux systems.

So there you have it, from the limited research I have done #! seems like an appropriate OS, but im not the expert.

Thank you for your time,
