TechFreaks has posted their article on Modding the Xbox in 10 Minutes
This is a follow-up article to my original Modding the Xbox in 10 Minutes. This guide will teach you how to install a larger hard-drive into your modded Xbox. A lot of people will ask for a legitimate reason for installing a hard-drive larger than the stock 8gb one. Here's a reason, games ripped to your Xbox load faster. Booting Halo 2 through the CD takes about twenty seconds to load; booting Halo 2 from the hard-drive takes about five seconds to load. There isn't this night and day difference in all games, but there are plenty of other legitimate uses to using a larger hard-drive in a modded Xbox.
