If you're a devoted Mac user like me, chances are, you'll have an old Mac sitting around somewhere, collecting dust. Don't give it away or send it off to be killed, repurpose it for use as a home file server! With simple configuration, you will be able to access its files wirelessly, from anywhere within your wireless network. Stream music, movies, and videos! Save files without wasting valuable hard drive space on your primary computer! The possibilities are (almost) endless! All you need is a Mac running OS X with an internet connection, so let's start!
Step 1: The Computer
To get your file server up and running, you only need two things: a Mac running OS X and an Ethernet Jack or AirPort card. Because the original AirPort card was releases in 1999, computers produced before then (like the Power Macintosh G3 I am using) will not support wireless internet connection. To remedy this, you will need an Ethernet jack somewhere in your house, and a cable to connect it to your spare computer.
Update 3-29: The "Ye olde I-don't-know-what" port is actually an ADB port.
