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

- handling lateral loads
- these won't be insignificant -- the monitors will be tipped downwards, and will be
supported primarily from behind
