I had looked at that senario, but getting the amount of storage I need will take a bit more, and it will be easier to add additional drives to the setup, aslong as I can squeeze drives in the box I can add controller cards.
I'm gonna boot the box up tonight and make sure everything is working, once done I will first look at freenas, if I cant get my head around that I will try Linux.
The whole idea behind my storage idea is that we have 3 PC's on the network and the kids are quite often shuffling through disc's to find the music/film/prog they want and this sometimes ends up with damaged disc's etc.
This will save my time and the kids, and give me a project to tinker over on the cold winter nights.
Thanks for all your replys, i'll keep popping back into this thread with more questions no doubt
