I'm all for case mods, and this one is just beautiful. ZapWizard over at the Bit Tech.net forums has constructed a redwood case for his 20GB 4th generation iPod. It really has that "executive" feel. Included in the forum posts is a nice photographic step-by-step for all you brave modders out there to copy.
Now, this isn't the first time we've seen wooden iPod case mods, but it's certainly the most beautiful.
