This is a good quality 10ft cable that I frequently use when the standard 6ft power cables (that usually come with computer equipment) are just not long enough. I particularly like to use these to wrap a few coils of extra cable behind a desk. That way, when it's time to pull the computer out for basic cleaning, maintenance, and testing, its easy to do so without unplugging it. A plastic coated clothes hanger can be made into a spring coil to strap onto the cable to give the coil shape and assist in keeping it untangled. If you do find yourself having to go deeper inside the box, just be careful to unplug the cord from the power supply at the back of the computer to prevent live current hazards while you are inside.
