The MacBook Air is thin, sleek and sexy, and we're not just talking about its chassis. Inside, there's a ton of metal and wires that make of the beefy innards of this relatively small notebook. iFixit did a tear down of the MacBook Air 11" model, and dissected each and every component contained inside the system. Here's a quick summary of what they discovered.
The large battery that fuels the Air is 35 watt-hours, which is relatively smaller than its predecessor, but since there isn't a spinning hard drive and the display is smaller this shouldn't present too much of a problem for battery life.
The 64GB flash storage board can be disconnected from the logic board, though this doesn't mean that it'll be easy for you to perform your own fixings--after all, you'll still have to purchase this completely custom part from Apple HQ. Inside, there are six main chips: four 16GB flash chips and an SSD controller manufactured by Toshiba, and a Micron DDR DRAM cache. The small form factor of the flash storage helps give the air the super-slim profile that so many have already fallen in love with.
As for the WiFi and Bluetooth chips, not much has changed. The onboard fan has definitely gotten smaller, and the MagSafe, USB port and sound card are all a part of one smaller board that connects to the logic board.
The logic board itself houses the following: Intel Core 2 Duo 1.4GHz processor (red), NVIDIA GeForce 320M graphics (orange), and 2GB of RAM (yellow).
