Motherboard Installation 

 

Your Guardian supports the following motherboard: ATX, BABY AT, 
MINI ATX, and MICRO ATX. The Index for the standoff holes are as 
follows. ( Imprinted on the motherboard tray are serial numbers that 
match certain motherboards ) 

A1~A9 ATX 
B1~B9 BABY AT 
M1~M9 MINI ATX 

U1~U7 MICRO ATX 

In order to install your motherboard go through the following steps: 

1.  Lay your case down so you can see the drive cages and the 

standoff holes on the motherboard tray. 

2.  Take your motherboard and match the standoff holes. 

3.  Remembering which standoff holes your motherboard 

needs, go ahead and screw the brass standoffs onto the 
motherboard tray. ( Note: If you find that some holes are 
unused, this is normal, this case is made to support for many 
motherboard sizes ) 

4.  Place your motherboard on top of the brass standoffs and 

attach it to the tray using screws provided.  

5.  Connect the 20-pin ATX power connector from your power 

supply (and AUX or +12V connectors if appropriate) to your 
motherboard.
