Now I'm by no means endorsing unsafe practises--but i just decased 2 ,14" monitors--switched their cases (one fit, the other didn't) and recased them--without discharging--when the monitor is unplugged there are no electrical hot spots on the board--the only thing with stored residual charge is the tube itself--if you handle it carefully, then you can do it without discharging it--If this makes you nervous, then discharge it--you still have a choice, make the one that feels most comfortable with your level of monitor experience.
