Sorry gang.. Was off watch for a few hours..
ChaCha, that is a difficult question on the ID of your computer. The info on the OS should tell you everything. Turn on the iMac (Tutty Fruity???) and click on the Apple icon, top left of toolbar, and click on the info. That should tell you everything.
If you brake down on the computer and cannot boot it up, get the box. It will have all your data on it. If you ever decide to throw away the box, peel off or cut out the various data labels which have your chassi number, build numbers, OS, etc, on it. (Build date, etc).
Basically, you have a 20" Aluminum iMac Unibody with OSX. I beleive you have a 2008 model as well, but not sure on the month.
Hope that helps. I think all their memory works about the same in the Alum. Unibody models. They use small chip sticks, similar to laptop sticks.
If you have a Frys Electronics, I think the memory is much less expensive there. They call them Sodium Sticks for some reason.. Sodium memory or sodium sticks.. Cant remember..

Thanks Lionheart!
So my Tutti Fruity needs the same sticks that you put on yours?
I want to order now or the next couple of hours...
I want to make sure I am doing it right...
Thanks again..

We don't have Frys here... we have CompUSA... or Nextag? ... and BB...
