I have five more Stormcast Eternals Liberators that I need to assemble, but I want to make these special. I've been googling conversions and it looks like most people just turn them into Space Marines or Inquisitor models. I did find a cool clockwork look that I really like. I have no idea where the hands come from though.
It's amazing what something as simple as a head and weapon swap can do for a model.
