I have been doing research and more research on how I can mount my two iMacs and cannot figure out if there's even a solution for my needs. I have a mid-2010 27'' iMac & a late-2013 27'' iMac. I want to have a dual mount like that from Monitors in Motion. Here's the problems I'm seeing though, my older iMac has very limited mounting options because of the weight and my new iMac needs some expensive modification to allow for VESA mounts? Tell me I'm wrong here. It appears mountmymonitor has a solution but I'm not crazy about that either. Is there not a solution to have a dual mount for BOTH iMacs (and potentially a 3rd) without dropping ~$2k? I mean is there even an option? I know it sounds crazy but I run a successful real estate pipeline company and hate my current setup as it's taking up far too much desk room. My ideal setup would be a dual mount, one which is somewhat stationary and another that is flexible so I can put it above or to the side of one of my imacs.
