I have an old iMac LCD (700 MHz G4) running OS 10.3.9 and my 40GB hard drive is almost full. Remember thinking that was huge and I'd never fill that sucker. I plan on keeping this baby as a web surfer and getting a laptop real soon. But I'm thinking it might be in my best interest to get an external hard drive in the meantime. For back-up and some extra space. I think photos, music, and Photoshop files make up the bulk of my current filled hard drive. Anyway, been reading a bit on the forums and not sure how comfortable I am buying an enclosure and putting the hard drive in there myself. Any recommendations for me? Brand, size, type, etc? Appreciate it if anyone can steer me straight because this is new territory for me.
