o, then it sounds exactly like you said. since apple wont fix it, i would prolly just find out where the noise is coming from, and then when i open it, hold below the point of the break. . . i wouldnt pay to get that fixed.
alternatively, u can open up the display, and maybe brace it. i took the bezel off my toshiba laptop before with no problems. on an apple tho, it may be a little more difficult. (like opening up the mac mini or ipod. . .)
