Hi I just bought a XPS system and it gave me the option of a additional case cover so I selected the plasma cover well I think the original XPS cover looks better but I thought the plasma cover was a snap on accessory cover but I cant seem to get it off! Is the orignal platinum xps cover under this one or did I mess up and now stuck with this plasma cover it didnt state anything when I was buying this that it would replace the OEM cover I just thought it was a added accessory thank you!
