My dad is giving me a Dell computer from his work on Saturday, and i figure i will end up making it into a home server for my place. I don't know what is inside of it right now, but i want to making server. I figure i will put three 500GB hard-drives in on a raid configuration, and get a new wireless N router to hook it into. so does anyone have any suggestions about configuring it, or what OS i should use on the computer? thanks
