Where can I find the specs on an iMac based off the serial, but not from the Apple Website itself?

Question

I have the serial, I want to verify the specs. I have tried the apple site and I get "cross - platform" specs for a range of units, but I want to know fot this specific unit.

FYI, I am purchasing this second hand. I know how to get the serial and verify the contents on the MAC, however, i know of some sites that provide this for you, however, I am unable to remember them at this time..

I need this information asap, so 10 points for the fastest response that gives me what I am looking for....

Answer 1
