The mSATA SSD unit appears to be assembled by Toshiba and is model number THNSNC064GMDJ.

There are six main chips on this custom board:

• Four Toshiba TH58NVG7D7FBASB 16GB flash chips which make up the total 64GB.
• Toshiba T6UG1XBG Solid State Drive controller.
• Micron OKA17 D9HSJ DDR DRAM cache.

The new SSD is 2.45 mm thick compared to the platter-based 5.12 mm thickness of the old Air's drive. Being smaller in two of three dimensions definitely helps the new Air achieve a super-slim profile.

The SSD weighs in at a mere 10 grams, compared to the 45 grams of its spinning cousin.

With the turn of a screw, out comes the wireless board.

Although it uses the newer Mini PCI Express form factor, the new MacBook Air uses the same Broadcom Wi-Fi/Bluetooth chip as the current lineup of MacBook Pros.

The model number is BCM943224PCIEBT2.

Three T5 Torx screws secure the fan to the upper case.

All of the cooling and ventilation in the MacBook Air is provided by the single squirrel cage fan.

It's thinner and tinier than the regular MacBook fans, just like everything else in this machine.

The MagSafe, USB port, and sound card are all part of one smaller board that connects to the logic board.

There's a blob of glue on the ribbon cable connection points that acts as an insulator. This may prevent some electrifying results from occurring should the contact points wear through the plastic sheeting and touch the aluminum case of the Air.

The Air sports a Cirrus Audio 4206ACNZ audio controller. We saw this same chip we found in the latest MacBook Unibody and Mac Mini

Three T5 Torx screws secure the ectomorphic logic board in place.

Like most recent Apple laptops, the heat sink comes out attached to the logic board. This is nice, as you'll only need to remove the heat sink and reapply thermal paste if you're replacing the logic board.

Unfortunately, like all previous MacBook Airs, the RAM is soldered to the logic board and is not upgradable. Apple does offer a 4GB RAM option at the time of purchase, but if you opt for only 2GB and decide you want more RAM later you'll be out of luck.

Our advice? Go for 4GB.

After removing eight T5 screws, the thermal paste on the CPU and GPU is the only thing remaining that affixes the heat sink to the motherboard.

The heat sink on the new MacBook Air is considerably smaller than all previous models. It weighs only 10 grams. Based on the tiny heat sink, it seems that the Ultra-Low Voltage 1.4 GHz Core 2 Duo CPU is a cool chip.

The logic board:

• Intel Core 2 Duo 1.4 GHz processor
• NVIDIA GeForce 320M graphics
• 2GB of Elpida J1108EFBG-AE-F RAM
• F2117LP 20H V
• TPS 51982 TI 06K

With the help of a plastic opening tool, the speakers come out next. These stereo units pump out... well... some mad wattage, probably around 1-2W.
