Basically I am getting the new imac and have a PC gaming tower (about 3 years old). I've decided that instead of putting money into a new tower I should just get an iMac. Yes i know PC's are better for gaming but I am a mac user and a graphic designer so all i use is mac professionally. I was wondering if instead of partioning the mac and starting over in windows. Is there a way I could somehow install bootcamp and run windows off my old HDD just like it was in my tower? As an external drive Does this make sense? Is it possible? Much thanks!
