i might buy a new internal hard drive for my powerbook (upgrade from a 60-100)......but i have a few questions for this.....how much would it cost to have apple install it at the genius bar (i dont have apple care), or should i just do it myself (how hard is it..ive built like 2 PCs before so i know how to install one more or less).....how much would you expect a 60gb powerbook hard drive to go for on ebay
