SATA Optical Drive
Installation Manual

Thank you for purchasing the Other World Computing Mac Pro
Serial ATA Optical Kit! This guide will walk you through the instal-
lation process step by step and get you up and running using your
new optical drive quickly.
Installation of the optical drive is straightforward but does contain
some dicult procedures. We highly recommend you thoroughly read
through this manual before beginning the installation to avoid any sur-
prises along the way.
ATTENTION!
You will be working in
close proximity to static
sensitive components. Take
precautions to not build up
static electricity.
You will need the following tools to perform this installation:
• A Phillips P1 Screwdriver
• A Phillips P0 Screwdriver
• You may need a thin pair of needlenose pliers, or a pair of hemostats,
depending on your Mac Pro and it’s time of manufacture.
Bring your Mac Pro up to a desktop level so you can work on it. You’ll be
leaving it in an upright position for this installation, but you won’t want
to be on the oor to do this job.

This manual is broken into 3 parts.
• If you own a Mac Pro 667MHz system made between August, 2006
and January, 2008, turn to page #3
• If you own a Mac Pro 800MHz system made after January, 2008,
turn to page #12
• The installation of the optical drive is the same for both of these
models. That portion of the assembly guide begins on page #16

Begin by removing the side door on your Mac Pro.
On the lower right, nd the memory bay.
Mac Pro 667MHz - Cable Installation

Remove the 2 memory riser cards, exposing the 2 Phillips screws shown here.
Remove the 2 Phillips screws. They are long and extend through the logic board and
into the back of the computer.

At the bottom of the memory bay, there are 2 more Phillips screws. They are a smaller
head than the ones inside the memory bay that you just removed. Use a Phillips #0
screwdriver to remove the screws.
There is one problem. On many machines, the screws were improperly installed. In-
stead of using loctite on the screw stando, Apple used loctite on the screws them-
selves, into the standos - without loctite on the standos that thread into the Mac
Pro’s chassis.
This means, when you try and remove the screws, the standos themselves that the
screws are screwed into turn. You may need to use a very thin pair of needlenose pli-
ers, hemostats, or even a thin at blade screwdriver to hold the hex-shaped stando
tight, while you loosen the Phillips screws.
A photo of this task being made look easy, at least if your screws are not improperly
installed as described above. Try and not strip the Phillips screw heads.

Make sure that the locking latch on the back side of the Mac Pro is lifted up. Then,
remove all 4 of the drive bays and set them aside.
Look inside the PCI Express bay at the top right of the Mac Pro. You’ll need to remove
items from this location next.

Using a Phillips P0 screwdriver, loosen the PCI Express cover retaining plate and
remove it. There is a tab at the top that the metal plate latches into, you’ll need to
unscrew the 2 screws and slide the plate down out of the tab.
Once the metal retaining plate is removed, remove the top PCI Express dead plate
cover from the top slot as shown. Set the dead plate cover aside, you’ll be using it in a
future step.

Remove your PCI Express video card. At the rear of the PCI Express slot, there is a small
plastic tab that you need to lift up to unlock the PCI Express card. While doing this, pull
gently on the card itself toward you and it will come free. Set the video card aside.
Immediately to the left of the PCI slots, at the top of the logic board, you will see this
Phillips screw. Using a Phillips P0 screwdriver, remove it.

Take the memory bay and gently move it to the right, towards the back of the com-
puter. You’ll be able to gently shake it and it will pop loose and move just enough to
expose a gap between the processor cover and the memory bay as shown.
Once the memory bay is moved, you can pull out on the bottom of the processor
cover on the bottom right, and gently remove it from the computer. It hinges up and
to the right as shown. It locks into the fan shroud on the left fairly tight.
