Great computer! Loving it. But, oh boy, the power cord is short. I use a Furman PM-Pro Series ii 20 amp power conditioner ( http://www.musiciansfriend.com/acce...ditioner-with-digital-volt-and-current-meters) for my gear, but now my iMac won't reach it. Is there a certain spec of extension cord I need? Will a Tripp-Lite surge protector suffice?
