When you say you want to remove it...is that because you want to replace it, destroy it, give it to someone, or something else? It's just there could be an alternative to actually removing it as Apple make it notoriously difficult to get inside any of their products without causing some damage.
If it cant be mended with a hammer then it will probably be an electrical fault mate, give it a few taps !
I know they're American but have you looked on here? http://www.macsales.com/ looks like they have kits for most repair/replacement jobbies.
