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 detailed instructions on installing your motherboard and peripherals, please refer to the user 's manuals which were supplied with with your components and drives.

Aria – MicroATX Cube Case

Your new case includes a preinstalled 300 Watt AR300 power supply, with Universal Input and Active PFC (power factor correction). The AR300 includes a quiet, low-speed 120mm fan that exhausts heat from the case.

The Universal Input feature allows you to connect the power supply to any standard power circuit between 90VAC and 265VAC, without having to worry about setting a voltage switch. The Active PFC feature improves the power factor of the power supply by altering the input current wave shape. This results in increased energy efficiency, reduced heat loss, prolonged life for power distribution and consumption equipment, and improved output voltage stability. Note: AR300's active PFC circuitry complies with European standard regulation code EN61000-3-2.

Setting Up

1.Place the case upright on a flat, stable surface. The power supply fan should be at the back, facing you.

2.Remove the screw from the rear of the case and remove the top panel by sliding it towards the rear of the case. Set the panel safely aside.

3.At the rear of each side panel, you'll find a locking tab. Remove both panels by squeezing the tabs and pushing the panels towards the front of the case.

4.Inside the case, you'll see the 8-in-1 card reader, the power supply, some wiring with marked connectors (USB, PWR etc.), an installed I/O panel and a power cord. You'll also find a bag of hardware (screws, clip-on standoff, a fan bracket, 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.Make sure you have the appropriate I/O panel for your motherboard. If the standard panel provided is not suitable for your motherboard, please contact your motherboard manufacturer for the correct I/O panel.

2.This case includes two brass standoffs and four clip-on standoffs, which are preinstalled. Line up the holes on your motherboard with the standoffs.

3.Install the motherboard by sliding it towards the rear of the case until the hook on each of the clip-on standoffs "clips" the holes on the motherboard. Not all motherboards will match with all of the provided standoffs; this is

normal, and won't affect functionality. (In other words there may be extra standoffs.) Remove unnecessary standoffs. There are two empty standoff holes in the case. Insert the extra clip-on standoffs from your tool bag into the holes should your motherboard require it.

4.Attach your motherboard to the brass standoffs with the provided Phillips- head screws. Your motherboard is now installed.

Connecting the Power and LED

The Antec AR300 is an ATX12V-compatible power supply. It has a single 20- pin Main Power Connector, a SATA Power Connector, and a 4-pin +12V Power Connector for the motherboard. It also includes five 4-pin Peripheral Power Connectors for your drives.

1.Connect the 20-pin ATX power connector (and +12V connectors if appropriate) to your motherboard.

2.Connect the Reset switch (labeled RESET SW) to your motherboard at the RST connector. Make sure the label always faces the front of the case.

3.Connect the Power Switch (labeled POWER SW) to the PWR connector on your motherboard.

4.Connect the Hard Drive Activity LED (labeled HDD LED) to the appropriate header on your motherboard.

5.To power the front decorative LEDs, locate the 4-pin Molex connector that's attached to the front bezel. Connect it to a 4-pin connector on the power supply. The LED's will light up when you turn on your system.

Connecting the USB ports

You'll find two 5-pin internal USB connectors (on separate cable sets) attached to the front USB connectors. Note: If you want to use both front USB connectors and the 8-in-1 card reader, your motherboard must have at least 3 internal USB headers.

Here's how to connect the internal USB connector to your motherboard headers:

Pin 1: USB Power - may also be labeled +5V

Pin 2: Negative Signal - may also be labeled P-, D-, USB0-, etc.

Pin 3: Positive Signal - may also be labeled P+, D+, USB0+, etc.

Pin 4: Ground

Pin 5: Ground (sometimes this pin is missing)

Note: Your motherboard's USB pin layout may differ from this common
