I have a 2014 iMac 5k that I will be replacing the screen. Since I’ll have it apart is it reasonable to remove the stand for a VESA bracket and does anyone know what part I’ll need to install? If it requires grinding/sawing on the computer I’ll pass on that part of the project. Your help is appreciated!

Apple never offered an upgrade kit for the ‘Thin Series’ models. You could order one with the VESA mount already present: Buy iMac with Built-in VESA Mount Adapter. While you can replace the foot, I don’t know of anyone ever trying to manufacture a VESA mount for this series If this is that important, I would sell my system and buy a new one with it. The amount of work and the risks are just to great to attempt.
