Also, I would like to add when I opened my unit up there was no metal shielding under the components is that a revision? Maybe someone already opened this up and forgot to put it back? Another thing: the cdrom unit itself doesn't fit flush with the back of the unit. I suspect it may be due to some really long solder blobs hanging from the bottom of the cd connector. Could someone take an up close picture of their units cd connector? Maybe level so I can see how much of the solder work hangs from the board its soldered to.
