In 2020 i got a 27" mid-2011 iMac with maxed out specs (i7, 16gb, 256gb ssd, 2tb hdd) this way (I was dumping my electronics there when I noticed some guy unloading the iMac). Of course at home I found out why it was dumped... the left half of the screen's backlight was defunct, turned out to be a torn off connector that I could resolder and it had the infamous radeon gpu issue: flickering, distortions and crashes depending on the chip temperature. Fixed that by rom hacking [1] a dell nvidia quadro MXM-card off ebay for 30€ and replacing the radeon module. I sold both the broken radeon mxm-module and the working iMac for 35€ and 380€. Succeeding with the repair was very rewarding, it will run for another couple years, I learned a few things along the way and made some buck.
