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.
At Antec, we continually refine and improve our products to ensure the highest

Nine Hundred User’s Manual
Nine Hundred – Gaming Case
The Nine Hundred 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 TruePower Quattro, TruePower Trio, or NeoPower power supplies for the latest
ATX specification compliance, broad compatibility, and power savings 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.
Attention:
The Nine Hundred comes with a top storage area. Antec does not recommend that
users put any liquid-containing items (drinks, ice cream, candles, perfume dis-
pensers, etc.) in this area. It was designed to hold your personal media player, digital
camera, keys, coins, etc.
Setting Up
1. Place the case upright on a flat, stable surface so that
the rear panel (power supply and expansion slots) is
facing you.
2. Remove the panel thumbscrews from a side panel and
open it by sliding it towards yourself.
Note: Place the panel thumbscrews carefully aside as they
are NOT interchangeable with the HDD cage thumb-
screws.
3. Remove the panel thumbscrews from the other side
panel and open it by sliding it towards you. Place the
screws carefully aside. Inside the case is the power sup-
ply mount at the lower rear of the case and the 5.25”
drive bay area with two HDD cages inside the bays. You
will also find some wiring with marked connectors (USB,
PWR etc.), an installed I/O panel and a toolbox contain-
ing more hardware (screws, brass standoffs, etc.)
Note: Don’t use your fingernail to pry or lift the panels.
