1 x Motherboard tray; 8 x 8mm M3 Standoffs and washers; 4 x M3.5 short cross head screws 
(attach mobo tray to up to 4 lower standoffs on some G5 models); 12 x 3mm acrylic washers (3 per 
M3.5 screw); 10 x M3 screws and washers (attach mobo tray to shelf attachment points on ALL 
models and to attach lower part of tray to case on some G5 models); 1x brushed aluminium 
backplate; 1 x acrylic cut out for I/O; 1 x fan support drilling template; 10 x M3 screws - attach 
backplate to G5; 10 x M3 Nyloc nuts - attach backplate to G5; 2 x M3 screws -attach cut-out for I/O 
to fan support; 2 x 10mm standoffs - attach cut-out for I/O to fan support 2 x M3 nyloc nuts - attach 
cut-out for I/O to fan support 

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. 

    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....
