How do I identify my iMac model from the choices listed for 20-inch, Early 2008: MB323 or MB324 or MB388 or MB 391? I have a 2.66 GHz Intel Core 2 Duo with 2 GB 800 MHz DDR2 SDRAM memory.
iMac, iOS 5, 2.66 GHz Intel Core 2 Duo 800MHz
Sorry: Just found the answer here :http://support.apple.com/kb/SP485
The 2.66 GHz model corresponds to MB324LL/A.
Here's another great (and free) resource for matching models to numbers and hardware configs:
A suggestion: your profile shows your operating system as "iOS 5". This system cannot run on any Mac computer, only "iDevices." Yours is probably Mac OS 10.something. Please do "About this Mac" from your Apple menu and edit you profile to reflect the OS version you see in the "about" window. That will get you help faster for future question because helpers don't have to ask about your OS version before answering.
