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 innovative Mini Skeleton case by Antec features an open-air design, giving you the freedom to
design your ideal Mini-ITX computing solution without the usual limitations that come with a standard
enclosure. This enclosure consists of two major parts – the Component Tray and the Frame. The
Component Tray is the main structure holding your motherboard, 5.25” device, HDDs and power
adapter/PCB. It can slide in and out of the Frame for component installation.
The Mini Skeleton comes with the EP-90 90-watt power adapter, which supplies your computer with
sufficient power to operate reliably.
Note: The Mini Skeleton comes without any panels or cover. Antec does not recommend that users
place any liquid-containing items (drinks, food, sprays, etc.) near it. It is highly recommend that you keep
your pets or children away from it.

Power
The EP-90 is rated at least 85% efficient at 100 VAC and 240 VAC input voltage and maximum
load.
A variety of industrial-grade safety circuitry will help protect your computer: OVP (Over Voltage
Protection), SCP (Short Circuit Protection), and OCP (Over Current Protection). Sometimes the
PSU will “latch” into a protected shutdown state. This means that you will need to power off the
adapter and clear the fault before it will function again.
There are no user-replaceable fuses in the EP-90.

ARDWARE INSTALLATION GUIDE
This manual is not designed to cover CPU, RAM, or expansion card installation. Please consult your
motherboard user’s 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.
2.1 R
EMOVING/REPLACING THE COMPONENT TRAY
1. With the rear of the case facing you, remove the thumbscrew at the left side of the Component
Tray.
2. Pull back on the rear of the tray until it stops.
3. To replace the tray, slide the tray back into the chassis from the rear until it locks into place,
then replace the thumbscrew on the left side of the Component Tray.
2.2 M
OTHERBOARD INSTALLATION
Slide out the Component Tray from the Frame as detailed in section 2.1.
1. Line up the motherboard with the standoff holes on the Motherboard Tray.
2. Screw in the motherboard to the standoffs with the provided Phillips-head screws.
Replace the Component Tray in the Frame as detailed in section 2.1.
Note: You do NOT need to install an I/O panel for the Mini Skeleton. Your motherboard should
come with one. Keep it in a safe place. You will need it if you decide to move your
motherboard to a traditional case in future.

2.3 5.25” D
EVICE INSTALLATION
1. In your tool bag, find one of the black screws and attach one to your 5.25” device at the right
upper side.
2. While facing the front of the case, insert your 5.25” device into the slot in the Component Tray
until it locks into position.
Note: It may be necessary to remove the side screens as detailed in section 2.5 to effectively
route cables to your device. Pause when the device is halfway inserted, connect the
power and data cabling, and then complete installing the device.
2.4 2.5” D
EVICE INTERNAL INSTALLATION
Your Mini Skeleton case has the ability to mount 2.5” hard drive devices vertically inside the
frame for convenient storage capacity.
1. In your tool bag, find one of the black screws and attach one to your 2.5” device at the front
screw holes.
2. While facing the front of the case, position the 2.5” device vertically and slide it into one of the
2.5” HDD mounting slots in the Component Tray until it locks into position (make sure the black
screw faces up).
Note: It may be necessary to remove the side screens as detailed in section 2.5 to effectively
route cables to your device. Pause when the device is halfway inserted, connect the
power and data cabling, and then complete installing the device.

2.5
2.5” D
Your Antec Mini Skeleton case has the ability to mount up to two additional 2.5” devices
externally on the Frame for additional storage capacity.
EVICE FRAME-MOUNTED INSTALLATION
1. Align your 2.5” device with the included 2.5” device mounting plates and secure them together
with the included screws.
2. Hook the mounting plate along the sides of the Frame.
Note: It may be necessary to remove the motherboard tray and/or side screens as detailed in
section 2.6 to effectively route cables to your devices.
2.6 R
EMOVING THE FRAME SIDE SCREEN PANELS
Removing the screens on either side of the Frame will allow access to the lower level of the
Component Tray for power and data cable routing.
1. Locate and simultaneously press inward the two tabs on the left and right of the screen panel.
2. Pull the panel away from the Frame.

USB 2.0 P
Connect the front I/O panel USB cable to the USB header pin on your motherboard. Check your
motherboard user’s manual to ensure that it matches the table below:
AC’97
Connected to your front I/O panel there is an Intel® standard 10-pin AC’97 connector and an
Intel® 10-pin HDA (High Definition Audio) connector. The pin assignments for these connectors
are as follows:
ORTS
AND HD AUDIO PORTS
I/O P
ORTS
You can connect either the AC’97 or the HDA connector, but not both at once, to your
motherboard depending on the spec 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.

P
OWER SWITCH / RESET SWITCH / HARD DISK DRIVE
Connected to the front of the Mini Skeleton-90 case Frame
are LED and switch leads for power, reset, and HDD LED
activity. Attach these to the corresponding connectors on
your motherboard. Consult your motherboard manual for
specific pin positions. 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 info on connecting LEDs to your
motherboard, see your motherboard user’s manual.
Note: There is no Power LED in this case. The illuminated case fans will turn on when there is
power to the computer.
