One / One S / One S3 User Manual

Disclaimer

This manual is intended only as a guide for Antec’s computer

enclosures. For more comprehensive instructions on installing the
motherboard and peripherals, please refer to the manuals that
come with those components.

Congratulations on your purchase of your Antec One / One S / One S3!

When building a PC, it’s important to use hardware you’re comfortable working with. From Antec, the

team behind dozens of award-winning enclosures since 1986, comes the One / One S / One S3, the
gaming case that gives you everything you need right out of the box at an attractive price. This enclosure
is stocked with features you value – USB 3.0, ample cooling and tool-less 5.25” & 3.5” drive bays – so

that you can put your PC together with ease and get to the fun stuff. If you’re looking for high quality

gaming essentials at an affordable cost, then this enclosure is the One for you.

The One / One S / One S3 does not include a power supply. Make sure you choose a power supply that is
compatible with your computer components and has a long enough power harness to reach your
motherboard and peripheral devices. We recommend our High Current Gamer or Earthwatts power
supplies for the latest ATX specification compliance, broad compatibility, and power savings capability.

At Antec, we continually refine and improve our products to ensure the highest quality. As such, your
new chassis may differ slightly from the description in this manual due to improvements applied for the
optimal building experience. As of the date of publication, all features, descriptions, and illustrations in
this manual are correct.
