WO HUNDRED USER’S
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 intended only as a guide for Antec’s computer enclosures. For more comprehensive
instructions on installing the motherboard and peripherals, please refer to the user’s manuals that come
with those components.
The Two Hundred does not come with a power supply unit (PSU). 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 TruePower or Earthwatts power supplies for
the latest ATX specification compliance, broad compatibility, and energy-saving capability.
Although care has been taken to prevent sharp edges in your Antec case, we strongly recommend taking
the appropriate time and care when working with it. Avoid hurried or careless motions. Please use
reasonable precaution.
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 take before installing the
motherboard. While installing hardware, keep your case on a flat, stable surface.
