exutable

Hello I have approximately 7 computer in my house and at this point I am interested in creating a file server that would host all the users files so they would be accessible at all times. I want it so that you can log in as a user at any of the computers and get to your files. I am sort of setting up a permanent LAN cafe in my house if you will. We are going to have all the games and what not on the workstations. What I am looking for is:

1. What operating system would I need on the server?
   
2. What would I need to install on the workstations to have a log-in screen everytime the computer boots?
   
3. What would I need to set up so that every time you do log in you have access to your files no matter what computer your on?

I am OK in Linux I am currently running a Web Server, Mysql Server and Counter-Strike server.

Thank you in advance
