I've got my b&w g3(450mhz) with 1gig of ram and I'm not using it for too too much, but what I am wanting to put it to use for is a file server to do this I would need to put in for now a 1tb drive and eventually 2. Hell, might as well future proof this concept (a little atleast) Lets say for argument sake that I'd need to put 4 drives in (2 for storage 2 for mirrored backup). So, my main questions are what would be a good (relatively cheap if possible) sata controller card that would support up to 2 drives as needing 2tb of mirrored backup isnt needed immediately and I could always add another in the future.

Also, it will be used for streaming SD/HD video and probally will be used for downloading/uploading torrents so would the 10/100 card in it be fine or would it be worth upgrading to a 100/100 card and if so recommendations that area to save from vncing into the box to do torrents does anybody also know of a client for osx that allows a web interface to download torrents?
