Just got a second hand macbook, white model (see attached pic) I keep hearing how easy it is to put in extra ram (I wanna go from 1 to 2 GB) Is it easy enough fro a complete novice to attempt on this model? I had a look on google, but there seemed to be a lot of different macbook body types. If it is easy, and I decide to go ahead, can anyone suggest a cheap source for the Ram its'elf? eBay, Amazon? Also, seeing as I hope to be running Photoshop, should I change the graphics card? Cheers guys!
