Here are three pictures I took of the internal of the new eyeMac G5 (iSight)
20". It differs from the eyeMac 17" considerably, as the HD is on
the left hand side and the processor is in the center, being cooled
by the center fan which draws its air from the back side vent. The
17" by comparison is just the opposite, and has the processor on the
left hand side, and the HD in the center cooled by the fan with the
backside vent. Other notes of interest, removing the front of the
eyeMac is not that hard, but to get to any of the components, you
must then remove the LCD screen which is sealed to the internals of
the case by lots of foil tape, and several hard to reach torex
screws. Once the tape and screws have been removed, you can lift up
the screen, but must be careful to unhook the remaining power and
video cables that run to the LCD. After removing the LCD you can
then see what is in my main-board picture.
If you have made it this far, removing the HD is straight forward.
Remove two screws on the left hand side of the drive to release the
bracket, and the drive lifts out. Also, for those who like to over-
clock, I included a shot of the Video Memory, in this case a Hynix
chip that is rated at up to 350Mhz based on a search of the part
number. Problem is, ATIccelerator II 1.0.6 does not work currently
on the x600 based iMacs. (Note: On Dec. 9th, ATIccelerator II version 1.06a was released with support for the iMac G5 (iSight) X600 graphics-Mike)
The Airport/Bluetooth card appears to be located under the right side
speaker.
On an aside, My iMac Rev B 2.0Ghz with the Radeon 9600 graphics has
Hynix Video Memory rated at 300Mhz, but is only clocked by Apple at
202Mhz by default.
So there is the potential for an almost 50% boost
in memory clock speed. I have used ATIccelerator on my Rev B and
clocked the memory to 297Mhz and have no problems with heat, or
artifacts. Usual disclaimers about over-clocking apply here...do at
your own risk...yada yada yada.
Hope this helps.

Here is the link I found for the Hynix memory:
http://www.hynix.com/datasheet/eng/dram/details/dram_04_HY5DU573222F.jsp
There were a least 2 chips, the one I photographed, and another only
a couple of inches away. But I did not remove the entire motherboard
to see if there were more on the back.
Looking back at the photos of the 17" eyeMac taken by Kodawarison
http://www.kodawarisan.com/imacg5_isight/imacg501i.html
they show 2 chips on the front side, and 2 more chips partially
obscured by a heat sink on the back side. They all appear to be
Hynix memory modules, and from their location in proximity to the
GPU, I would assume that they are all 4 memory chips, meaning each
one is 32MB.
Just a note that I have read and enjoyed your site for years, and I'm
just glad to be able to contribute something that your readers may
find of use, or at least interesting.
Best, Kurt
