My sis is a nurse and deals with ice users at the hospital.
She hates it. She's told stories of multiple burly security guards trying to hold them down so they can jab em with something to put them out. She says that if they even suspect ice use they have to call the guards straight away to get someone in to help em out.
They don't feel pain. They don't feel anything except rage. And they can lash out big time with no provocation.
It's a terrifying substance.
Are you sure they are ICE users? Doesn't sound like ICE to me.
One of those situations when the hdd bays in the case didn't quite align with the psu cables (without me rummaging through stuff). The result is a vibration free mounting situation in the direct path of intake air flow.
