Hey guys I'm considering on getting an external or internal drive for my macbook, i'm pretty new to this stuff so i don't know what im doing haha. well i have these questions: -if i get an external can i then break it out its enclosure and install it in my macbook later? -is installation easy? -what type of HDD will i have to buy? and could you recommend any good ones? atm i have a 160gb in my macbook, but i'd prefer something like a 320gb or anything above that. price really isn't an issue, but the cheaper the better.
