Installing the Motherboard This manual is not designed to cover CPU, RAM, or expansion card installation. Please consult the motherboard manual for specific mounting instructions and troubleshooting. Before proceeding, check the manual for your CPU cooler to find out if there are steps you must do before installing the motherboard. Lay the case down so that the open side is up.

SATA connector is designed to connect to a standard SATA connector on your motherboard. This will allow high speed external hard disk enclosures such as the Antec MX-1 to run at the same speeds as if the hard disk were installed inside the case.

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. You can connect either the AC’97 or the HDA connector, but not both at once, to your motherboard depending on the spec of the motherboard.

External 5.25” Device Installation Note: The HDD cages each occupy three consecutive drive bays, and will block installation of larger devices such as optical drives, so please plan ahead before installing your drives. Remove both side panels per the instructions in Setting Up.

Cooling System The Big Boy 200mm fan: Antec understands your desire for the coolest gaming system. That’s why the Twelve Hundred comes with a Big Boy 200mm blue LED fan. This fan has a three-speed switch that lets you choose the speed best suited to your need and a switch to turn on or off the blue LED.

High if you choose to connect the fan(s) to a fan control device or to the Fan-Only connector found on some Antec power supplies. A fan control device regulates the fan speed by varying the voltage, which may start as low as 4.5V to 5V.

There are two optional 120mm fan mounts—the side fan (on the left side panel) and the middle fan (at the rear end of the HDD cage). We recommend using Antec 120mm TriCool™ fans and setting the speed to Low. These two fans should be installed so that the air is blowing into the case.

Side Air Filter – There is a filter located in the side fan bracket. It is located on the inside of the side panel, so you must open the side panel to access it. Remove the filter by sliding it out of the bracket. From time to time it will be necessary to wash the installed air filters.
