Screws for assembly
Do NOT Overtighten The Screws! — Stop turning once resistance is felt; do not exceed one-quarter turn
🧭 Tip: Fasteners differ in length and head shape - lining them up side by side can help with identification
Use the Mat
Build on the included mat to protect panels from scratches!
Optimize Airflow
For less dust, set intake airflow through the Side Panels with dust-filtering holes, and exhaust through the Top & Bottom Panels
🧭 Tip: Top/Bottom Panel Intake Setups Are Supported.
Dust filters are also available as an accessory for this type of airflow setup
Install PSU Bracket
Choose either the SFX Bracket or ATX Bracket for installation
Use your power supply screws to secure the bracket — use 3 screws ONLY to avoid interference
Secure PSU to MB Plate
Check orientation — the MB Plate's flat side should face the PSU
Install Motherboard
Install CPU Cooler
Install GPU
🧭 Tip: Plug in the PSU cables to the Motherboard, GPU, and other components before the next step - this will save a lot of hassle later
Install PSU Inlet Cable
Pass the PSU inlet cable C13 male head through the Rear Panel
Install Rear Panel
The GPU IO Bracket Tabs must be fully inserted into the Rear Panel slot
Do NOT remove the GPU Lock Bar, removal makes installation harder
Check the GPU is seated properly before tightening the screws
Install the Front Panel
Make sure this screw is aligned with the hole on the ATX/SFX PSU Brackets
Using a longer screw at this location will damage your power supply!
🧭 Tip: Orient PSU fan away from the solid Front Panel for better airflow
🧭 Tip: Orient PSU fan toward the vented Front Panel for better airflow
Install Bottom Panel
Install Fan Bracket
Side Fan Bracket Mount — Remove the Front & Rear Panel Foams
Side Fan Bracket Mount — Adjust up & down for the best fit
Top Fan Bracket Mount — Keep the Front & Rear Panel Foams in place
Top Fan Bracket Mount — Adjust left & right for the best fit
🧭 Tip: Don’t tighten the screws yet!
Install the Fan Bracket with screws loosely in place
Install the Top Panel and make sure it opens/closes smoothly
After checking the Top Panel fit, fully tighten the bracket screws
Install Side Panels
Insert the bottom edge of the Side Panel into the Bottom Panel slot
If not fully seated, the top panel will not close properly
Put the spacer in place before installing the panel. Do not remove it.
🧭 Note: Using the glass window side panel on the M3 Round Kit will affect side airflow, which may reduce overall thermal performance.
Final Step: Install Top Panel
Insert the Top Panel’s front edge (tongue) into the Front Panel recess
🧭 Tip: Make sure both side panels are fully seated first. If misaligned, the top panel won't close properly
Secure the top panel by inserting the included Thumbscrews into the Rear Panel holes and tightening by hand
🧭 Tip: These screws prevent accidental sliding or lifting of the top panel during use or transport
