3.
Line up the motherboard with the standoff holes. Determine which holes line up and
remember where they are. (Not all motherboards will match with all of the provided
screw holes, and this is not necessary for proper functionality.) Some standoffs may
be pre-installed for your convenience.
4.
Lift up and remove the motherboard.
5.
Screw in the brass standoffs to the threaded holes that line up with the motherboard.
6.
Place the motherboard on the brass standoffs. Screw in the motherboard to the
standoffs with the provided Phillips-head screws.

The motherboard is now installed.
Installing the Power Supply
1.
With the case upright, place the power supply on the bottom of
the case.
Note: Power supplies with fans on the bottom of the power
supply will need to be mounted so that the fan is facing the
top of the case. The Three Hundred Illusion provides mounting
holes for power supplies with standard mounting layouts to be
installed upside up or upside down.
2.
Push the power supply to the back of the case and align the
mounting holes.
3.
Attach the power supply to the case with the screws provided.
Connecting the Ports and LEDs
Note: Please refer to your motherboard user's manual for specific pin outs or location of
front panel connectors.
1.
Connect the Reset switch (labeled RESET SW) to the motherboard at the RST
connector. Polarity (positive and negative) does not matter for switches.
2.
Power Switch (labeled POWER SW) connects to the PWR connector on the
motherboard.
3.
Connect the Power LED connector to the Power LED connector on the motherboard.
For LEDs, colored wires are positive (+). White or black wires are negative (–). If the
LED does not light up when the system is powered on, try reversing the connection.
For more info on connecting LEDs to your motherboard, see your motherboard user's
manual.
4.
Hard Drive LED (labeled HDD LED) connects to the drive activity header on your
motherboard or RAID card.
