We don’t have a Mid 2011 iMac GPU board guide. But this guide will get you mostly there [guide|7575] Follow it to Step 33. Finish removing the logic board out noting the cables you still need to disconnect from the backside. With the logic board out you can then remove the GPU and its heat sink. Do make sure you apply a fresh coat of thermal paste on the GPU and replace the thermal pads on the V-RAM chips. Don’t use thermal paste on them as you need a special gapping paste which is not as good as the pads.
