V3

Congratulations on your purchase of the Antec Twelve Hundred V3.

Antec’s Twelve Hundred V3 gaming case combines maximum performance, cooling and compatibility in
a full-tower package. Thirteen drive bays, space for graphics cards as large as 17.5,” a CPU cutout, an
internal 2.5” SSD drive mount and newly integrated USB 3.0 round off a robust foundation for your
components. The Twelve Hundred V3 features a top Big Boy 200™ blue LED cooling fan, two rear blue
LED 120 mm fans and three front blue LED 120 mm fans. Apart from standard size power supplies, the
Twelve Hundred V3 can accommodate Antec’s CPX form factor PSUs.

The Twelve Hundred V3 comes without 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, High Current Pro or CP
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. It’s possible that
your new case will 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.

Disclaimer: 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.
