It's not difficult at all, depending on how familiar you are with opening up your Mac and knowing what to plug and unplug and such. What is the size of the hard drive that you'll be putting into the Mac? Some Macs will only read up to 125 GB of hard drive space? Will you be adding this to the hard drive that you already have inside or will this hard drive be replacing the one you have? Are you familiar with jumpers at all? These are tiny plastic tabs that slide on to tiny pins which are located between the 4 big pins where the power on the hard drive goes and the two rows of pins where the ribbon cable connects to.
