Instructions.
The case should be stripped of all electrical items and fittings prior to kit installation
so as to avoid problems with drilling swarf. The directions below do not detail the
full stripping process.
BACKPLATE
1. With the G5 stripped and fans removed, offer up the backplate to the rear of the G5 and
do a test fit. Test fitting means simply laying the backplate against the rear of the G5
and ,using the PCI slots as a reference and starting from the upper right hand corner
place the short M3 screws through aligned holes in the G5 backplate.
2. With the new backplate lying against the G5 back, this will show you where you will
need to cut away material. I suggest scribing around the inside of where the fan holes will
be, as well as around the I/O cut out. REMEMBER you must keep the material of the G5
backplate that you are going to secure the screws to, so it is a good idea to mark with a
pen or similar the position of the mount holes. The panel should sit like this:

3. Once you have marked up the areas to be removed, you can start cutting the G5 back.
If in doubt under cut and then go back and cut more later - you can always remove
material, but putting it back is not so easy....
4. The Picture below shows an example of the material to be cut away. Note that in this
picture, more material than is necessary has been cut away - this is because this test
case previously had a different style of backplate attached to it - so you can make
neater smaller cuts than shown here. Importantly: the mesh needs to be cut right up to
the wall of the PCI compartment as shown, and one full column of holes needs to be left
on the left and the right hand side. Also, make sure one row of holes remains above the
top of the power plug outlet. Generally leave as much material of the original back intact
as you can.
5. Once you have made the cuts test fit the new back. This time, once you have loosely
fastened the new back plate into place offer up a 120mm fan to the hole and see if all
fits well. If there is too much of the original back to allow the fan assembly to fit, then
make a note of where the problem is, take the backplate off and do any needed extra
cutting.
6. Take the trim plate and arrange the 6 long standoffs like this:

6. Having done this you can now fasten the backplate to the rear of the G5. There are 6
M3 countersunk bolts and nyloc nuts which fix the blue circled areas of the plate. The
trim plate standoffs fix to the areas circled in red and attach through the front with 6
more M3 screws.
7. Now the interior looks like this:
11.You have now finished all the adaptations to the back of the G5 and can place your
120mm fan into position. However, if you are also fitting the motherboard tray then we
suggest you leave the fan placement until later. Fan fixing is standard - simply use the
fixings that came with your 120mm fan to fasten it to the backplate.

MOTHERBOARD TRAY
1. Turning to the inside of the G5 we come to the fitting of the motherboard tray. First
though, there are some “non” standoffs that need to be removed from the G5 case
completely. These are the button headed (i.e. not threaded) standoffs that were used to
locate the original motherboard and which allowed the motherboard to slide in elongated
slots. The photograph below shows one example of these standoffs - all similar
standoffs to these should be removed.
2. Now is a good time to just do a quick test fit of your motherboard tray into the G5. Take
the tray and place the tray in the G5 as shown below. Note that standoff positions in the
G5 will vary according to model. The principle though is that standoff posts within the
motherboard outline (red) and not used to fix the tray in position need to be removed or cut
down.

3. For a few G5s, you may find you need to attach the motherboard tray to standoffs that are inside
the footprint of the ATX motherboard. For instance, in the motherboard tray shown below, the
tray had to be attached at the points arrowed. For these two mount points the standoffs had to
be reduced in size by the use of a dremel tool or hacksaw so that when the motherboard was
mounted to the tray there was no chance of them interfering with it.

The top of the tray will be fixed in position by using these shelf mounting points:
3. Having done the test fit, now take the board out of the G5, detach the red circled
standoffs (you can simply remove them by tapping them lightly with a hammer to give a
sideways jolt) peel off the protective film from both sides of your motherboard tray and
put it back into the case.
4. You can now secure the top of the tray by screwing in three of the supplied countersunk
M3 screws to the three shelf mounting points shown, while the board is secured in place at
the bottom by using other washers and screws from the fixings pack. In the example
shown in the photos it is secured by putting three of the supplied acrylic 3mm washers
over each standoff and then using the supplied M3.5 screws to hold the board securely in
place. Other models may use M3 screws and washers to hld the board in place.
[Note: If you bought an ATX board, fitting is exactly the same except there are two
additional top mounting points and two more M3 black screws supplied.]
5. Now screw the supplied standoffs into the brass inserts on the motherboard tray to
match the pattern of mounting holes present on your motherboard - note that for ATX trays
all mounting points for ATX/mATX and ITX boards have been provided with threaded
inserts and that for the mATX trays, mounting points for mATX and ITX are provided.

Mounting your motherboard.
With the tray in position and the backplate secured, you can complete your buildup.
When fitting the motherboard, it is suggested that you do so with the trim plate already in
position. Just push the metal IO shield for your motherboard into the rectangular opening
formed by the trim plate and the end wall of the PCI slots. As the fit is quite tight against
the PCI slot bracket you may find that shaving a small amount off the end of the metal IO
shield nearest to the PCI slots gives the best fit and placement
Loosely associate the metal I/O shield with the rear ports of the mobo and feed the mobo
into position on the tray.
Screw the motherboard to the tray with the rest of the M3 countersunk screws that have
been supplied.
With everything secured, you can now (if you have not done so already) fit your 120mm
fan and grill.
Sit back and admire your handiwork!
