Broken optical drive on my old machine I don't have the heart to replace with a flashy new model, libraries are wayyy too big for the 160gb original HD and don't use compact disks too often anymore, so decided to add a TB
so easy! Doesn't even screw in just sits right where optical drive was.
Remember to keep the PATA cable from the optical drive as you do not get a new one! And as always with older MacBooks pre unibody don't mix up the screws as they are different sizes and shapes
