Ok, so I have an aluminium aswell but I bought this one too. The polycarbonate one. I threw money away and I am not going to let it be wasted for nothing. In my country there is no Apple sStore so I bought this 2009 macbook model from a reseller. First I had problems with the charger, they gave me a new one since it wasn't my fault and now I have a new problem. Take a look: What should I say to the reseller? My Mac is still under warranty.
