You can't see it, but the power strip is on top.....so one can get to the switch easily, the power cable is very visible, and the outlet it goes to in the closet is fed by a separate circuit that used to power a water pump (when the house was built, the water pressure wasn't quite up to snuff; since things have built up in the area, that changed and the pump went bye bye after it froze up), so there is a seperate breaker in the garage.

 

I grew up on movies like 'Colossus: The Forbin Project' . Never ever have computers you can't pull the bloody power cord on.....
