Hi, I am really new to mac and trying to order one MBP 17inch soon for College... first question I have is what case I should get to protect the palm rest, trackpad, keyboard, screen , bottom and the top.. second, I am trying to decide on the screen: either glossy or anti-glare... which one should I get?? (I am mostly going to use the laptop in my room and outside probably) third, I am trying to order 500gb 7200rpm to save money for ssd later. If I get the SSD and install it, does that avoid my warranty? and any SSD recommendations?? Thank you in advance!!
