HumptyDumpty

Thank you so much for your guide! I was challenging myself to do it without cheating, but couldn't figure out how to release the bottom plastic layer from the main unit inside after I undid the 3 Torx screws. Thankfully you avoided me having to break the whole unit by showing where the central screw hidden beneath the S/N 3 barcode sticker was and that it was Philips not Torx, and I can now pinch the A1027 wifi card and use it in my G5, instead of relying on ageing ethernet! Bless you kind folks!
