Hi. First of all. I'm from Iceland and we do not have an official apple store. We do however have few stores that sells Apple products. I went to one store and was asking if I could self change the battery, RAM, HDD if I bought the new Macbook Pro. He said that if I would open just one screw it would void the warranty. Only stores with approval from Apple could do that. Is that really true? It is almost twice the price to buy battery, RAM and SSD from that store.
