Thus was Jonas' thought process (maybe not verbatim) when he came across this 500mhz G3 ibook with a busted display. Other than the screen, the computer functioned perfectly, making it a good server candidate.
He removed the display, optical drive and battery. Next he whittled the case down to the bare minimum that would contain the remaining parts. Finally, he went to a used book store and found a hardcover book that was slightly larger than the resized laptop and cut out all of the pages.
He then used some plastic and velcro to secure the 'book in the book, put it on the shelf and the iBooklet server was born. He claims that there have been no heat issues. Still, I wouldn't go to sleep with that thing running.
