I remember seeing on a forum about someone under the name Scott, that happens to make his own custom bracket, for the Imac 5k with the non-removable stand? I cant remember the thread though, but the bracket basically replaces the hinge mechanism, and works the same as the built in vesa-mount. So i am just wondering whether anyone happens to have one of these? Thanks in regards.
Is this what you are looking for? 5K iMac hinge replacement for VESA mount compatibility?!
