Now that the finished version of the Oculus Rift is here, you might be wondering what's inside and how easily you can replace parts if something goes terribly wrong. You won't have to guess after today, though: the repair-it-yourself crew at iFixit has torn down the virtual reality headset. The production model isn't quite as easy to fix as the original developer version due to its "intricate design," but it's still accessible -- if an earpiece breaks, you might have a chance at replacing it on your own.
