This is one of the passages about the iBook G3 Clamshell modification project, of which a logicboard of Intel i5 was being installed into the classic Apple iBook G3 Laptop.
iBook G3 is a series of consumer portable laptop launched by Apple. It was first introduced by Steve Jobs during the keynote presentation of Macworld Conference & Expo in New York City on 21 June 1999.
The first generation iBook has a clam shell outlook, so it was called "iBook Clamshell" to distinguish from its succeeding models. Its body is translucent either in Tangerine (Orange) and Blueberry (Blue) colour. It has a PowerPC G3 CPU, USB, Ethernet, modem ports, an optical drive and designed with integrated wireless networking.
