Last week, Apple updated its lineup of MacBook Pros with quad core processors and Intel's new Thunderbolt high speed I/O technology. iFixit.com, a site DIYers must visit for repairing their tech gadgets, grabbed an early updated 15-inch MacBook Pro and proceeded to tear it apart and show what's inside.
This gallery shows off the Thunderbolt hardware used for the first time ever, a controversy over the amount of thermal paste used, and many other details involved in the laptop's construction.
