Hey guys, Tomorrow I will be upgrading my eMac to a DVD drive instead of a cd drive, just so I can install leopard. The drive will be removed after the install, as it was in my other computer. My questions: 1. What safety precautions should it take with the CRT? I know that CRTs emit radiation, so if the case is open, will I get exposed to it? Also, I know about the high voltages and had it unplugged for 12 hours. 2. If I were to buy an external USB dvd drive, would the emac be able to boot off it natively? Thank You!
