Have you always dreamed of having your own Linux file server but were worried about hardware or energy costs? Well with 150$ or less you could build your own portable, energy efficient and powerful Linux file server. All you have to do is buy a Western Digital MyBook World Edition and perform some hacker magic which will grant you root access to the device. The device runs Linux out of the box and is quite jam packed with features but you can’t use any of that functionality without liberating your device. Without voiding you warranty you are just limited to the functionality revealed through the device’s web panel. After you unlock your device you can do almost everything with it. You could even install bit torrent on it and have it download torrents for you all day and control the torrents remotely via ssh or a torrent web panel.
