Okay I know many of you are very computer savy. I have been taking apart and toying with computers since I was about twelve so I know my way around the kitchen but I have a few questions about networking. Right now I am networking three computers at my house wirelessly and I have an old pentium two dell that I re-built to standard office computer specs just sitting around. I would like to turn this computer into some sort of server seeing as it is not a terrible computer and I hate looking at it sitting still going obsolete every day. Can anyone tell me what sort of server would be most beneficial in this scenario (Internet gateway? File?)and how to go about setting it up? (Or any links or websites I could read about it on)
