New Solution Series User’s Manual  
NSK 4000 II / NSK 4480 II / NSK 4480B II  
Mini Tower Case  
This case is designed to meet Intel’s Thermally Advantaged Chassis (TAC) 2.0 design  
guide requirements.  
While the NSK 4000 II does not offer a PSU, the NSK 4480 II and the NSK 4480B II come  
with an EarthWatts 380 watt PSU. The PSU features Universal Input and Active Power  
Factor Correction (Active PFC). It conforms to the ATX12V v2.2 specification and is cooled  
by a single 80mm fan. Two +12V output rails deliver safer and more reliable output to  
your system’s components. Higher energy efficiency reduces power consumption by up to  
25%, saving you money on your electric bill. EarthWatts power supplies have achieved 80  
PLUS® certification, the highest independent standard in power supply efficiency. In addition,  
EarthWatts includes a variety of protective circuitry: OPP (over power protection), OVP (over  
voltage protection), and SCP (short circuit protection).  
The power supply comes with a main power switch. Make sure you turn the switch to the  
ON ( I ) position before you boot up the computer for the first time. Normally, you won’t  
need to switch to the OFF ( O ) position, since the power supply includes a soft on/off  
feature. If the computer crashes and you can’t shut down using the soft switch, switch the  
main power to the OFF ( O ) position, then reboot.  
For models designed for sale in the European Union:  
Antec power supply models feature Active Power Factor Correction (Active PFC) circuitry  
in accordance with European standard regulation code EN61000-3-2. By altering the input  
current wave shape, Active PFC improves the power factor of the PSU. A better power  
factor increases energy efficiency, reduces heat, improves output voltage stability and  
prolongs the life of your equipment.  
Although care has been taken to prevent sharp edges in your Antec case, we strongly  
recommend taking the time and 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.

Hardware Installation Guide  
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.  
2.1 Setting Up  
1. Take the case out of the box. Remove the styrofoam and plastic bag.  
2. Place the case upright on a flat, stable surface so that the rear panel (power supply and  
expansion slots) is facing you.  
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 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.).  
2.2 Motherboard Installation  
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. 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 motherboard.  
6. Place the motherboard on the brass standoffs.  
7. Screw in the motherboard to the standoffs with the provided Phillips-head screws.  
2.3 3.5” Device Installation  
There is one 3.5” drive cage inside the case. It can hold two external 3.5” drives and three  
internal 3.5” hard disk drives (HDDs).  
1. Remove the screw that fastens the cage to the case. Slide the cage out of the case.  
2. Mount your external 3.5” drives into the top two drive bays and internal drives into the  
other three drive bays that have rubber grommets. Load the drives from the back, lining  
them up to the front of the drive cage.  
3. With one hand supporting the drive, fasten the drive to the cage with the screws  
provided.  
4. Slide and fasten the cage back to the case.  
5. Find a small 4-pin connector on the power supply and connect it to the male 4-pin  
connector on the floppy drive.

6. Connect the appropriate connector(s) from the power supply to the hard drive(s).  
2.4 5.25” Device Installation  
There are three external 5.25” drive bays.  
1. Looking from the rear of the case you can see metal grills covering the 5.25” drive bays.  
Carefully push a screwdriver through the metal grill and gently push the plastic drive bay  
cover outwards until it comes off.  
2. Using your hands, twist the metal plate back and forth until it breaks off.  
Note: Don’t break off the metal grills covering the drive bays that you are not using  
now. Be careful of the newly exposed metal where the grill was attached, as these  
areas are likely to be sharp.  
3. Fasten the 5.25” device into the drive bay with the screws provided.  
4. Repeat the same procedure for other devices.  
5. Connect the appropriate connector from the power supply to the device.

You can connect either the AC’97 or the HDA connector depending on the model of the  
motherboard. Locate the internal audio connectors from your motherboard or sound card and  
connect the corresponding audio cable. Consult your motherboard or sound card manual for  
the pin-out positions. Even if your system supports both audio standards, you may only use  
one connector.  
3.3 Switch and LED Connectors  
Connected to your front panel are LED leads for power and hard disk activity and switch leads  
for power and reset. Attach these to the corresponding connectors on your motherboard.  
Consult your motherboard manual for specific pin header locations. Polarity (positive and  
negative) does not matter for switches. For LEDs, colored wires are positive ( + ). White or  
black wires are negative ( – ). If the LED does not light up when the system is powered on,  
try reversing the connection. For more information on connecting LEDs to your motherboard,  
see your motherboard manual.

3.4 Rewiring Motherboard Header Connectors  
There may come a time when you need to reconfigure the pin-  
out of a motherboard header connector. Examples could be  
for your USB header, audio input header, or some other front  
panel connector such as the Power Button connector.  
Before performing any work, please refer to your motherboard  
manual or your motherboard manufacturer’s website to be sure  
of the pin-out needed for your connector. And we strongly  
recommend making a notated drawing before beginning work  
so that you can recover if your work is disturbed.  
1. Determine which wires you need to remove in order  
to rewire your plug to match the USB pin-outs on your  
motherboard (refer to your motherboard manual). Working  
on one connector at a time, use a very small flathead  
screwdriver or similar tool to lift up on the black tab  
located beside the gold posts (squares). This will allow  
you to easily slide out the pins from the USB plug.  
2. Working carefully so as not to damage the wires,  
connectors, or pins, slowly remove the pin from the  
connector. Repeat these steps for each wire you  
need to change.  
3. Working carefully so as not to damage the wires, connectors or pins, slowly reinsert the  
pin into the correct slot of the connector then snap closed the black tab that was lifted  
in step 1. Repeat these steps for each wire you need to change.  
Cooling System  
4.1 Rear Exhaust TriCool™ Fan  
The NSK 4000 II / NSK 4480 II / NSK 4480B II comes with one 120mm TriCool™ fan  
pre-installed. This fan has a three-speed switch that lets you choose between quiet,  
performance, or maximum cooling. (See specifications below.) The fan is installed so that the  
air is exhausting. Connect a large 4-pin connector from the power supply to the male 4-pin  
connector on the fan.  
Note: The default setting of the fan is Low. We recommend this speed for maximum  
quiet computing.  
Note: The minimum voltage to start the fan is 5V. We recommend that users set the fan  
speed to High if you choose to connect the fan to a fan control device or to the Fan-Only  
connector found on some of Antec’s power supplies. A fan-control device regulates the fan  
speed by varying the voltage to it. The voltage may start as low as 4.5V to 5V. Connecting a  
TriCool™ set on Medium or Low to a fan-control device may result in the fan not being able to  
start. The already lowered voltage from the fan control device will be further reduced by the  
TriCool™ circuitry below 5V.

4.2 Front 80mm Intake Fan  
An optional 80mm fan can be installed to pull air in at the bottom front of the case. A  
mounting bracket is provided for this purpose.  
1. Squeeze the upper right and left sides of the fan cage together to release the tabs. Once  
loose, you should be able to pull the cage back and out of the case.  
2. Drop the fan into the cage and push it in until it clips in. No screws are needed. The  
front fan should be installed so that air is blowing into the case.  
3. Reattach the cage/fan assembly to the case, making sure to not pinch the wires of the  
fan. There are slots near each corner to put the wires through (any corner will work,  
find the one that’s best for you).  
4. If you’re using a 4-pin fan, connect a 4-pin large white connector from the power  
supply. If you’re using a 3-pin fan, connect the 3-pin connector to a motherboard fan  
header.
