SUMMARY OF ASSEMBLY STEPS
Before starting assembly in the case, test all other components for functionality. If using a
PCIe gen 4 graphics card and motherboard with the included PCIe gen 3 riser, the
compatibility mode must be set to gen 3 in BIOS. Doing so will require performing the
first boot with integrated graphics (if available) or with the graphics card plugged directly
into the motherboard without a riser.
1. Install your CPU, CPU cooler, memory, and M.2 drive onto the motherboard, attach it to
the tray
2. Insert riser into the PCIe slot, flip over the tray, install graphics card and screw in riser
3. Install IO shield and install that subassembly back into the main body of the case with the
top PSU holder attached
4. Install power supply, 2.5” drive, attach all cables
5. Install front struts, install power button into the front panel and plug it in without
installing the front panel, install side panels, then the front panel

POWER BUTTON
Remove the bottom bracket temporarily to install the power button. Use the
hex nut to fix the button in place, then reinstall the bottom bracket.
Consult your motherboard manual for the front panel header pin layout and
plug in the power button before proceeding to the next step.
Button is enlarged for clarity. Hold the
button from the opposite side and secure
it using the nut without the rubber ring.
This step will require some force.

SIDE PANELS
Power button cables must be plugged into the motherboard prior to this step.
The side panels have three positions. Spacing them farther away from the
body of the case will result in quieter operation.
0 mm spacing
2 mm spacing (experimental)
4 mm spacing (experimental)
If using the experimental 2 or 4 mm
spacing, adhesive rubber feet may be
inserted between the side panel
and main body to help keep
the side panels straight.

FRONT PANEL
Slide in the front panel while carefully inserting the power button’s cable into
the case. Secure the front panel to the frame at the bottom and the top.
For an easier fit, re-position the brackets on the inside of the front panel
away from the edges.
Install the included rubber feet after this step.
