Installing The Motherboard - Antec OVERTURE II User Manual

At Antec, we continually refine and improve our products to ensure the highest quality. So it's
possible that your new case may differ slightly from the descriptions in this manual. This isn't
a problem; it's simply an improvement. As of the date of publication, all features, descriptions,
and illustrations in this manual are correct.
This manual is intended only as a guide for Antec's Computer Enclosures. For
more comprehensive instructions on installing your motherboard and peripherals,
please refer to the user's manuals which come with your components and drives.
OVERTURE II – PIANO-BLACK MEDIA CENTER CASE
Your new case features a quiet ATX12V version 2.0 compliant SmartPower2.0 power supply.
[Applies only to models designed for sale in the European Union:
SmartPower 2.0 series power supply models designed for the EU include Power Factor Correction
(PFC) circuitry in accordance with European standard regulation code EN61000-3-2. By altering
the input current wave shape, PFC improves the power factor of the power supply and results in
increased energy efficiency, reduced heat loss, prolonged life for power distribution and con-
sumption equipment, and improved output voltage stability.]
SETTING UP
1. Place the case on a flat and stable surface. Note: the Overture II includes a special
version SmartPower 2.0 power supply that intakes cool air from the bottom of the case
and exhausts it through the side vent of the case. DO NOT place the case on a
carpeted floor or soft surface that could block the airflow to the power supply.
2. Note (not applicable to models designed for the European Union): Before installation, check
the red voltage switch setting on the power supply. The voltage switch is located behind the
power supply exhaust vent at the left side panel (with the front bezel facing you). It should
match your local voltage (115V for North America, Japan, etc. and 230V for Europe and many
other countries). If it doesn't match, please change the setting. If you don't you could damage
your equipment and void your warranty.
3. Remove the two thumbscrews at the rear from the top panel. Remove the panel by sliding it
towards the rear of the case and lifting it up. Set the panel aside.
4. Inside the case you should see the power supply, some wiring with marked connectors (USB,
PWR etc.), an installed I/O panel and a power cord. You will also find a bag of hardware
(screws, brass standoffs, plastic stands, etc.).

INSTALLING THE MOTHERBOARD

This manual does not cover CPU, RAM, or expansion card installation. Please consult your motherboard
manual for specific mounting instructions and troubleshooting.
1. Lay the case down, with the open side facing up. The drive cages and power supply should
be visible.
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. Line up 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 functionally. (In other words, there will likely be extra holes.)
4. Remove your motherboard by lifting it up.
