Hi there. I see you noted the antenna cover was difficult. But can you remember how things are connected on thre antenna? I've just got a machine, and someone has broken all the antenna connectors. The antenna doesn't cost much but all come with isight cables too. I'm hoping you can just disconnect and remove the isight cable that comes with the new antenna and just connect the one that is already there.

I have just tried this, and it's perfectly do-able if you just remove the fan and disconnect the iSight cable. Once removed, you can access the memory. It's behind the board but can put fingers in to unclip and slide out. Saves almost all the steps apart from the screen.
