For the 2008 ram note that the usable Ram is indeed 6 GB via the two RAM slots as I stated.
indeed the Ram for the 2008 Penryn processor iMac is NOT laptop Ram but rather the :800 MHz PC2-6400 DDR2 SDRAM
| RAM Type: |
PC2-6400 DDR2 |
Min. RAM Speed: |
800 MHz |
| Details: |
Supports 800 MHz PC2-6400 DDR2 SDRAM. Also see:How do you upgrade the RAM in the "Aluminum" iMac Core 2 Duo models? How much RAM of what type do these systems support? |
| Standard RAM: |
2 GB |
Maximum RAM: |
6 GB* |
| Details: |
By default, 2 GB of RAM was installed as two 1 GB SO-DIMM modules. No slots free.
*Apple officially supports 4 GB of RAM, but third-parties have been able to upgrade the system to 6 GB of RAM using one 2 GB and one 4 GB memory module.
Site sponsor Other World Computing sells iMac memory, as well as hard drives, accessories, and other upgrades. |
Also note that the 2gb of extra ram is useful in the Penryn 2008 iMacs because of the onboard video uses the system ram for graphics functions.
This is accurate information as stated by me, I have this as one of my machines. Also this is substantiated by the following two sites.

Indeed the sound is not upgradeable , but as you say it is convenient that the port is optical toslink supported.
