Concerns I still have about making sure this can be done safely: - prevent electrocution - cover all internal metal pieces with thick cardboard, and secure with duct tape? - use a GFCI -- this is specifically what they're designed for http://en.wikipedia.org/wiki/Residual-current_device - handling lateral loads - these won't be insignificant -- the monitors will be tipped downwards, and will be supported primarily from behind
