Hey guys, my friend got a old MacBook that needs some upgrading. I'm not sure what year model it is but it is 2.0GHz Duo Core with 2GB ram 1066. But is it upgradable? (Or is the body sealed tight?) And does anyone know what year model this is with a 2.0GHz Duo Core? Can I buy this? http://www.amazon.com/Kingston-Modu...I3Q0/ref=sr_1_1?ie=UTF8&qid=1310106881&sr=8-1 How fast will it run once installed a 8GB or maybe a 4GB? Thanks!
