I am thinking about changing the HD and adding RAM into my Macbook.. (2.0GHz, C2D, 80GB HD, 1GB RAM). My questions are: 1) What is the biggest and fastest HD available for the MB (w/o being a battery hog). 2) What the maximum amount of RAM supported by the MB (can someone link me to it?) Here's my plan for changing/upgrading these parts.. is it workable? Take out the MB's original HD, and put in the new one. (Before this, having the OS X Disc 1 in the drive). Boot off the disc, and install OS X onto the new HD. (the HD now should have OS X successfully installed) Buy an enclosure for the old HD, and plug it in FW400/USB2.0 and just mainly transfer music files onto the new HD. (will it recognize it? basically just plug-in-transfer) After this, proceed to ram (Pretty confident in doing). So, again.. will that plan work? 1) Can you link me to (good quality) RAM for the MB 2) The biggest and fastest HD supported (w/o being a battery hog [doesn't have to be the most expensive one either ) Thanks guys.. hopefully this made sense to you.
