MacBook Pro 17" Unibody SuperDrive area change

I have finally replaced my 3 year-old MacBook Pro 15" with a MacBook Pro 17" unibody. When opening the machine up to replace the hard disk, I noticed that the area around the SuperDrive looks different than it does in earlier disassembly photos. Take a look at Step 12 in this disassembly page, and compare it to the photos of my machine.

Here's the SuperDrive area from the old disassembly page:

Here's mine, below. Notice the new black box, which is actually screwed onto the SuperDrive housing. I unplugged the cable and moved it from the groove it was set into, which is why it wanders off the screen.

I pulled the cable out a bit for this photo

The little black box is attached to the SuperDrive housing by tiny Phillips screws, and would be easy to remove, for those of you (us) thinking about putting two drives into the machine.

**UPDATE**: Step 11 of the MacBook Pro 17" unibody disassembly page states:

> It's very nice that Apple moved this out of the display assembly (where it is located in the MacBook Unibody and 15" MacBook Pro Unibody). No longer does a Unibody owner need to replace their entire display assembly ($$$) when their Bluetooth goes out.It's very nice that Apple moved this out of the display assembly (where it is located in the MacBook Unibody and 15" MacBook Pro Unibody).

It looks like the black box is the Bluetooth board.
