Mine is a G4 so it would work right? I've been look at the Samsung 16GB SSD for the main drive then a CF adapter from addonics and two CF cards.. or just dual samsung ssd's or i could get the 250GB Western digital drives. but i worry about heat with two regular hard drives. so i'm struggling on what to go with.... i'm definitely leaning towards at least one 16GB SSD and then maybe wait till prices come down and get a bigger ssd for storage?? my main thing now is, i want to just have a light fast laptop for school... i can use my new macbook for everything else. I think my main hard drive now is about to go so i'm gonna back it up and then go from there really soon... so i would love some more input from you
