Installing the Power Supply
1.
With the case upright, place the power supply on the four silicone pads on
the bottom of the case.
Note: Power supplies with fans on the bottom of the power supply will need
to be mounted so that the fan is facing the top of the case. Twelve Hundred
V3 provides mounting holes for power supplies with standard mounting
layouts to be installed upside up or upside down.
2.
Push the power supply to the back of the case and align the mounting holes.
3. Attach the power supply to the case with the screws provided.

Flexi Drive Bay System
The Twelve Hundred V3 comes with twelve 5.25” external drive bays at the front of the case. There are
three HDD cages preinstalled inside the bottom nine 5.25” bays. Each HDD cage occupies three
consecutive 5.25” drive bays and can house three hard disk drives. For maximum flexibility you can
mount the HDD cage anywhere within the external drive bays (i.e., you are not limited to the bottom six
bays).
Possible Drive Bay combinations include but are not limited to:
• External 3 x 5.25” + internal 9 x HDD – default
• External 6 x 5.25” + internal 6 x HDD – by removing one HDD cage
• External 9 x 5.25” + internal 3 x HDD – by removing two HDD cages
• External 12 x 5.25” by removing all three HDD cages
Note: There is a middle fan bracket pre-installed on one of the HDD cages. Install a 120 mm fan to the
bracket so the air will be blown into the case, if you decide to use the HDD cage as a cooling duct to cool
your graphics card or CPU. However, this will stop you from installing your hard drives into this cage.
Remove the middle fan bracket from the HDD cage if you decide to mount your hard drives into this
cage.
• External 3 x 5.25” + internal 6 x HDD + cooling duct – by adding the middle fan to one of the HDD cages
(see Cooling System)
• External 6 x 5.25” + internal 3 x HDD + cooling duct – by adding the middle fan to one of the HDD cages
(see Cooling System)
