i have this 512 mb pc133 ram thats a tad to tall for my 12' 900mhz G3 iBook. it really only hits this metal thing on the way down but it would fit if i get it past it. there is no way to move the metal thing with out taking the whole iBook apart. My question is, since the memory has a sticker that says IBOOK on it, is it made for the 14' iBook? Does the 14' have more clearnce room? i got the memory from some guy on craigslist that said he took it out of his iBook. Im not sure what size or model though.
