I'm wanting to build a home server. I also know next to nothing about servers. I would like to to primarily be a file server, with a handful of drives in a raid 5, and after that I would like it as a gateway(?) running dansgaurdian to filter my kids' internet usage. They are getting small laptops for Christmas so it's an issue my wife and I need to sort out.
Is there some idiots guide, tutorial type instruction somewhere that can help me sort out what I need and how to do it? I probably won't get to it for at least a few more months but I'd like to have as much figured out before I dive in and start buying stuff.
