iBook upgrade

Decided to replace the hard drive in my iBook (when I bought it over a year ago I thought the drive was plenty large - yeah right). I got one of these puppies and will attempt to put it in there myself, using this beautiful guide the good people from PB FixIt in San Luis Obispo have put online. I have good hopes but in case you won't see anything new here for a while, something may have gone horribly wrong.
