Turn & align the I/O & PCI-e ports of the motherboard to the bottom left.
Align the mounting holes on your motherboard to the PSU leg.
Secure that leg to the motherboard with M3 screws.
Repeat steps 2 & 3 for the remaining motherboard legs.
Important!
It’s crucial that you cover any of the stand-offs that won’t be used with insulating material before you install the motherboard to the motherboard shelf.
Any stand-offs that isn’t used and not covered properly will most likely cause your motherboard to short out, causing critical damage to it!
Hardware used
9-11× M3 screws
Tip
Have the motherboard legs stand up when mounting for best support.
The leg marked with: “Middle” isn’t required when installing an ATX motherboard. That leg is only required when you have a motherboard of the type EATX or SSI-EEB.
