ASSEMBLY 

– instructions. 

 
First take Part B (MB pack panel) and Part C (I/O panel).  Place part C so that the flanges are up and the I/O 
slots are down on a flat surface.  This would be the opposite of how it shows in the picture above.  Next take 
Part B and align it so the single flange on it is pointing down.  Rotate Part B so that the 120mm fan hole is on 
the left side.  Then place Part B on to of Part C and align the clearance holes on the part with the threaded 
inserts on the flanges of the I/O Panel.  Then take 7 x 6-32 computer screws from Pack (F) and fasten the back 
panel to the I/O panel.  Put one screw in at a time without tightening until all screws are in place.  After this 
your assembly of the two parts should look like the picture on the next page.
