Ignoring all manufacturer warnings, we are removing the non-removable battery. Hold your breath!

There are three tri-wing screws holding the battery to the Unibody case.

Removed the battery! That was pretty easy.

It's only a matter of time until you'll be able to buy this battery online from companies like us.

Removing the battery in the 17" is reminiscent of the MacBook Air-- several screws to remove the lower case, a few screws on the battery, and it's free.

The battery is Apple model #A1309, 7.3V 95Wh (12820 mAh).

Tree huggers everywhere will be relieved to know that it "contains no Mercury (Hg)."

The battery weighs 20.1 ounces (1.25 pounds or 570 grams). That's 20% of the computer's weight!

The Bluetooth board is right behind the optical drive, next to the hinge.

It's very nice that Apple moved this out of the display assembly (where it is located in the MacBook Unibody and 15" MacBook Pro Unibody). No longer does a Unibody owner need to replace their entire display assembly ($$$) when their Bluetooth goes out.

It has an Anatel logo on it: BCM93046MD MINI 003WWA080264 FCC iD:QDS-BRCM1037.

Like the other Unibody machines, the Airport card is in the display assembly clutch cover.

The 8x slot-loading SuperDrive (DVD±R DL/DVD±RW/CD-RW).

The internal design of this machine is pretty consistent with the 15" MacBook Pro. We'll be posting some part comparison shots later to show relative sizing.

The component density is amazing. Here's a large version.

There are four Samsung K4J10324QD-HC12 chips, likely video RAM for the NVidia 9600 chipset.

The Sunon manufactured fan says 'MagLev' on it. That's interesting! Part #: MG45070V1

Sunon's site says, "By using magnetic levitation force (MagLev), these fans feature zero friction with no contact between shaft and bearing. With excellent rotational stability, the MagLev fan eliminates vibration and typical wobble and shaking typically experienced in fan motors. MagLev also provides excellent high temperature endurance that results in long life."

Apple's used similar fans in MacBooks in the past.

Removing the Phillips screws securing the perforated metal covers to the Unibody. These covers seem to protect the ribbon cable connections for the trackpad, keyboard, express card, and the serial ATA hard drive. Apple hasn't used metal shields like this before.
