ANAGEMENT
There is a cable management compartment behind the 3.5” drive cage. 
You can tuck or route excess cables in this compartment. This will keep 
the cables from interfering with airflow in your case and help with 
cooling. 
1.  Open the side panel as described in section 2.1.  
2.  Locate the cable management compartment with cable ties 
located behind the walls of the external 3.5” drive cage. 
3.  Tuck or route your excess cables to the compartment. 
4.  Use cable ties to hold them in place.

NSTALLATION
The Sonata Proto comes with four motherboard standoffs 
already screwed in to the most common mounting locations. 
1.  Lay the case down, with the open side facing up. 
The drive cages should be visible on the right side of 
the case, with the power supply in the upper left. 
2.  Make sure you have the correct I/O panel for your 
motherboard. If the panel provided with the case 
isn’t suitable, please contact your motherboard 
manufacturer for the correct I/O panel. 
3.  Align your motherboard with the standoff holes and 
remember which holes are lined up. Not all 
motherboards will match with all the provided 
holes; this is normal and won’t affect functionality. 
4.  Now remove your motherboard by lifting it up. 
5.  Install standoffs if needed and put the motherboard 
back in. 
6.  Screw in your motherboard to the standoffs with 
the provided Phillips-head screws.  
Caution:  Make sure to remove any unused motherboard standoffs. They may come into contact 
    with the back of the motherboard and may electrify your case exterior if left connected.
