I am looking for my 2nd mac. Just got a 12" powerbook and love it. Now, because of my 60GB hard drive, I am looking for a 2nd desktop. Ideally the machine would be good enough for video editing and thats it. In fact I don't even have a strong desire for Final Cut. iMovie will suffice. What is the minumum hard drive to do home movies? What is the minumum processor speed? G4/G5? What is the minumum video card? When I say minumum, I do not mean the lowest specs that can manage, but the lowest specs that will do a decent job. I already know that I do not need a DUAL processor, but would like some help deciding from iMovie users.
