I have an older iMac with a 3rd party VESA adapter, which holds the iMac through a circular hole in the back of the original stand. I actually prefer this because the foot of the iMac functions as a little shelf below. I usually set my phone or occasionally an external drive on it. The adapter has the same metal finish so it looks like it could have been an original part.
