Installing the Motherboard
This manual does not cover CPU, RAM, or expansion card installation.
Please consult the motherboard manual for specific mounting instructions and
troubleshooting.
1.
2.
Lay the case down with the open side facing up. The drive cages and power
supply should be visible.
Make sure you have the correct I/O panel for the motherboard. If the panel
provided with the case isn’t suitable, please contact the motherboard
manufacturer for the correct I/O panel.
3.
Line up the 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.
5.
Remove the motherboard.
Screw the brass standoffs into the threaded holes that line up with the
motherboard. Note: Do not over-tighten the standoffs. Some standoffs may
be pre-installed for your convenience.
6.
7.
Place the motherboard on the brass standoffs.
Screw in the motherboard to the standoffs with the provided Philips-head
screws. The motherboard is now installed.

Connecting the Power and LED
1. Connect the 24-pin Main Power Connector and
the 4-pin +12V connector to your motherboard as
needed. If your motherboard uses a 20-pin connec-
tor, detach the 4-pin attachment on the 24-pin power
connector. (see pictures 1 and 2).

motherboards

motherboards
2. Connect the Reset switch (labeled RESET SW) to your motherboard at the
RST connector.
3. Connect the 4-pin molex connector from the front display to a 4-pin molex
connector on the power supply.
4. The Power Switch (labeled POWER SW) connector connects to the PWR connector
on the motherboard.
5. The Hard Drive LED (labeled H.D.D. LED) connector connects to the hard drive
activity header.
Power supply 3-PIN fan signal connector
A three-pin signal connector with blue and black wires is available to connect the
power supply to one of your motherboard’s fan connectors (Note: Some motherboards
have a dedicated fan connector labeled PWR-FAN or PSU-FAN that is specifically for
the power supply). This connector is for monitoring the power supply’s fan speed
only. It is optional—the power supply and its fan will operate normally whether
this cable is connected to your motherboard or not.
The fan speed can be monitored through the BIOS or special monitoring software
that came with your motherboard. To ensure proper monitoring of the power supply
fan, please check your motherboard manual.
Note: At low temperatures, the fan may run as slow as 750 RPM ( 10%). At
these speeds, some motherboards may not properly detect the fan speed and may
generate false warnings of fan failure.

Connecting the USB Ports
You will find a single 10-pin connector on a cable attached to the front USB ports.
This is an Intel® standard connector that is keyed so that it can’t be accidentally
reversed when connected to a proper Intel® standard motherboard header. Connect
the 10-pin connector to the motherboard headers so that the blocked pin fits over
the missing header pin.
Note: Please check the motherboard manual for the USB header pin layout and
make sure it matches the table below. If it does not match this Intel® standard,
search for part number 30095 to order a USB Internal Adapter Cable. This adapter
will allow you to connect the front USB to your motherboard on a pin-by-pin basis.

Connecting the IEEE 1394 (FireWire®, i.Link®) Port
You will find a single 10-pin connector on a cable attached to the front IEEE 1394
connection. This is an Intel® standard connector that is keyed so that it can’t be
accidentally reversed when connected to a proper Intel® standard motherboard
header. Connect the 10-pin connector to the motherboard header so that the
blocked pin fits over the missing header pin.
Note: Please check the motherboard manual for your IEEE 1394 header pin layout
and make sure it matches the table below. If you intend to connect the front
FireWire port to an IEEE 1394 add-on card that comes with an external-type IEEE
1394 connector, you will need a FireWire Internal Adapter. To order one, please
part number 30031. This adapter will allow you to connect the front IEEE 1394
port to the external-type connector.

Connecting the Audio Ports (AC’ 97 and HDA)
There is an Intel® standard 10-pin AC’ 97 connector and an Intel® 10-pin HDA
(High Definition Audio) connector, either of which can be connected to your
motherboard depending on the spec of the motherboard.

Locate the internal audio connectors from your motherboard or sound card.
Consult your motherboard or sound card manual for the pin-out positions.
3.5” Device Installation
There is a hard disk cage right under the external 5.25” drive. You can mount four
hard drives using the trays inside it.
1.
2.
Open the front bezel as described in Setting Up section.
Loosen the two thumbscrews. Swing open the fan cage and gently lift the
cage upward to remove it. You will see four drive trays with soft silicon
grommets inside the cage.
3.
4.
Squeeze the metal clips on each side of the tray and slide the tray out.
Mount your hard drive into the drive tray through the bottom rubber
grommets with the special screws provided. Note: Don’t over-tighten the
screws. Over-tightening the screws will reduce the vibration and noise-
dampening ability of the rubber grommets.
5.
6.
Slide and lock the tray back into the case.
Find the appropriate power connector on the power supply and connect it to
the connector on the device.
7.
8.
Repeat the same procedure for the other devices as necessary.
Put the front fan cage back to the case. If you plan to mount the optional
92mm case fans, do it now. See The Cooling section for fan installation.
5.25” Device Installation
There are four external 5.25” drive bays (one with 5.25” to 3.5” Adapter).
Carefully remove the metal plate covering the drive bay.
4
1.
Take two plastic drive rails and mount them to the sides of the 5.25” device.
Make sure to use the front set of the screw holes on the drive rail.
Also make sure the end of the drive rail is angled away from the device and
facing forward.
2.
3.
4.
Slide the device into the drive bay until you hear a click.
Mount the other devices accordingly.
Find the appropriate power connector on the power supply and connect it to
the connector on the device.
To install a floppy or other external 3.5” device to the 5.25” to 3.5” Adapter:
1.
2.
3.
Slide the Adapter out.
Place the drive to the adapter and fasten the drive with screws provided.
Find a 4-pin floppy power connector on the power supply and connect it to
the male 4-pin connector on the devices.
Cooling System
The TriCool™ fan:
The case includes one 120mm TriCool™ fan installed in the rear. This fan has a
three-speed switch that lets you choose between quiet, performance, or maximum
cooling. (See specifications below.) The fan is installed so that the air is blowing
out of the case. Connect a large 4-pin connector from the power supply to the
male 4-pin connector on the fan.
Note: The minimum voltage to start the fan is 5V. We recommend that our users
set the fan speed to High if you choose to connect the fan to a fan control device
or to the Fan-Only connector found on some of Antec’s power supplies. A fan-
control-device regulates the fan speed by varying the voltage to it. The voltage
may start as low as 4.5V to 5V. Connecting a TriCool™ set on Medium or Low
to a fan-control device may result in the fan not being able to start. The already
lowered voltage from the fan control device will be further reduced by the TriCool™
circuitry below 5V.

The Front 92mm fans
You can install two 92mm fans to the fan cage in front of the internal 3.5” drives.
These fans must be installed so that the air is blowing into the case. We recom-
mend using Antec 92mm TriCool™ fans to balance quiet performance with maxi-
mum cooling. See our web site for product information.
Note: Please choose your fan speed wisely. In most cases, a medium or even low
speed setting will be enough to supply adequate cooling.
