Antec NSK 4480B User Manual

2

Although care has been taken to prevent sharp edges in your Antec case, we 
strongly recommend taking your time and the appropriate care when working with 
it. Hurried or careless motion and use of excessive force, particularly when you are 
working in areas you cannot see clearly, are but a few examples of activity that 
should be avoided. Please use reasonable precaution.

1.    Take the case out of the box. Remove the Styrofoam and plastic bag.
2.

Place the case upright with the power supply fan at the back facing you on a 
stable flat surface.

3.

Remove the two thumbscrews that fasten the top cover onto the case. These 
are the only screws you need to remove to open the case. Set these screws 
aside and keep them separate from the other screws.

4.    Slide the top panel toward the rear of the case and lift it up to remove.
5.

At the top of the each side panel, in front of the power supply, there is a 4” 
wide tab. Using this, lift and pull the side panels out to remove. 

6.

Inside the case you should see the power supply, some wiring (LED’s, etc.), 
an installed I/O panel, a power cord and a plastic bag containing more 
hardware (screws, brass standoff, plastic stands, etc.).

This manual is not designed to cover CPU, RAM, or expansion card installation.
Please consult the motherboard manual for specific mounting instructions and 
troubleshooting.

1.

Lay the case down so that the open side is up. You should be able to see the 
drive cage and power supply. 

2.

Make sure you have the appropriate I/O panel for the motherboard. If the 
panel provided is not suitable for the motherboard, please contact the 
motherboard manufacturer for the correct I/O panel.

3.

Line up the motherboard with the standoff holes, and determine which ones 
line up and remember where they are. Not all motherboards will match with 
all of the provided screw holes, and this is not necessary for proper 
functionality.) Some standoffs may be pre-installed for your convenience.

4.    Lift up and remove the motherboard.
5.

Screw in the brass standoffs to the threaded holes that line up with the moth-
erboard.

6.    Place the motherboard on the brass standoffs.
7.

Screw in the motherboard to the standoffs with the provided Phillips-head 
screws.

8.    The motherboard is now installed.

The power supply conforms to the ATX12V Version 2.2 standard. If the 
motherboard has a 20-pin power receptacle, detach the 4-pin attachment on the 
24-pin power connector, see pictures 1 and 2. Before you 
connect the power supply to any devices, please consult 
the appropriate user manuals for the motherboard and 
other peripherals.

1.

Connect the 24-pin Main Power Connector and 
the 4-pin or 8-pin connector to the motherboard as
