Before You Begin
Please take the following precautions:
Handle all PC components and cards with care.
Hold cards and processors by their edges to avoid damaging components.
To avoid damaging components by electrostatic discharge, periodically ground yourself by
touching an unpainted metal surface or by using a wrist grounding strap.
Before connecting cables, make sure the connectors are correctly aligned.
Consult the documentation of your motherboard and other components for specific installation
instructions and troubleshooting.
When routing cables…
Route and bundle PSU and case cables to reduce clutter for a cleaner look and to improve
airflow. The case is designed with cable pass-through cutouts throughout and space to conceal
cables under the right side panel (as seen from the front). Use the provided nylon zip ties to
hold the cables in place.

Remove the case side panels
Put the case upright on a stable, flat surface with rear facing you. Remove the thumbscrews from both
side panels and store them in a safe place. Remove each panel by slide the the panel toward the rear.
Install the motherboard
The CR280 is compatible with mini-ITX motherboards enabling you to build a high-performance
compact PC. Let’s install one.
1. Install the CPU, CPU cooler and memory on the motherboard.
Refer to your CPU and motherboard documentation how to mount the CPU and its cooler on
your motherboard. If you are using a liquid CPU cooler you may find it easier to install it after
the motherboard is installed in the case.
2. Install the I/O panel.
Your motherboard should have come with a standard I/O panel that shields and exposes the
rear motherboard connectors out of the back of the case. From inside, snap the I/O panel into
the cutout in the rear of the case.
3. Attach the motherboard to the case.
The CR280 comes with four mounting standoffs for a mini-ITX motherboards. Slide the
motherboard into the I/O panel and then align the motherboards screw holes with the case
standoff. Attach the motherboard to the standoffs with the provided motherboard
thumbscrews.

Install Hard Drives and SSDs
The CR280 has one 3.5” drive bays and two 2.5” drive bays. These bays are located in the compartment
under the motherboard.
To install a 3.5” hard drive
The 3.5” hard drive will be held in place by two pins on the side of the case and by pins a retaining bracket.
1. Remove the thumbscrew and retaining bracket. Take note of the pin locations under the lip of
the case.
2. With the circuit board facing up, align the holes on the side od the drive with the case pins.
Then carefully slide the drive into position.
3. Align the retaining bracket pins with the holes on the other side of the drive. Slide the bracket
back in place and tighten the thumbscrew.

To install drives into the 2.5” mounts
The CR280 case has two mounts for 2.5” drives such as solid state drives (SSD). The mounts are two sets of four
screw standoffs.
To mount a 2.5 drive:
1. In the motherboard compartment of the case, place the 2.5”drive on one set of drive
standoffs. This may require sliding the drive under the case front fan.
2. From other side of the case, screw the drives in place with the provided Philips screws.
