My second was the 2009 first Gen i7 27” iMac. I think it ran me about 2700. Still use it today. I have a thread on the boards about the upgrades I did to it when the GPU crapped out on me in I think fall 2016.
Doubled the RAM from the apple states max of 16gb to 32gb. A 2010 GPU. A higher speed CPU than apple ever sold for it. And a 2tb hybrid drive.
