Um, yeah? Lots of pictures on the 'net

It's easy to find those. A quick google for "
imac desk mount", and you will see dozens of different setups.
You will even see some with those cobbled-together setups using the iMac foot adapted to a VESA mount.
My earlier post was not an attempt to make you think that you haven't looked for those photos --- only pointing out that the VESA mount model is quite versatile, adapting to a large number of VESA-type mounts, and also that the actual mount used is entirely up to user, and not really limited by the iMac.
