We wanted to see how the iMac clock battery (190 mAh) stacks up with the 17" Unibody's behemoth (12,820 mAh), so we put them next to each other:

• 17" Unibody wins.

Most components are buried beneath the LCD assembly. This isn't a new design for Intel iMacs, but is certainly not as convenient as the rear-accessible iMac G5.

Unscrewing the two T6 screws securing the display data cable.

After removing the two screws, we pulled the connector straight up, wiggling back and forth as necessary.

The LCD panel is held in place with eight 11.8mm T9 Torx screws.

The LCD in this iMac is not LED backlit, but uses the more traditional CCFL backlight.

There are five cables (four inverter cables and one temperature sensor) to disconnect before the LCD panel can be removed from the iMac.

This display is an AU Optronics M302EW02. The manufacture date shown on the back of the LCD is 09/04, that's probably the 4th week of 2009.

Removing the desktop 320GB SATA hard drive.

After disconnecting the temperature sensor cables, we rotated the long black clip toward the drive to unlock it, then swung it to the side.

We then unplugged the SATA cables and pulled out the hard drive without removing any additional screws.

This screw-less design for the hard drive is nice, but unfortunately getting to to this point requires removing 21 screws.

Each speaker is attached by one screw and one connector cable.

Only the right speaker needs to be removed to gain access to the logic board, but we removed them both.

The Bluetooth board is the blue board in the top center.

The 802.11n card is on the right with two antenna wires running to it from below the logic board.

Removing the logic board.

First off, let's disconnect 13 connectors.

Next, we remove 10 T10 Torx screws... (Second image)

...and 2 T8 Torx screws.

It's out! (Third image)

Apple's flat-panel iMacs have always been an interesting cross between a laptop and a desktop. This iMac features a laptop-style optical drive and RAM, but a desktop hard drive.

This is a 12.7mm SATA 8x double-layer SuperDrive.

As far as we know, this leaves the AppleTV as the only shipping Apple product with a PATA drive.
