Assembly Guide
Step 1 – Assemble motherboard panels
Begin by placing the 2 motherboard panels together that the motherboard will rest upon. (The 3 triangles on one piece should fit well in the sockets of the other piece) and screw them together by using 3x M3x5 screws.
Step 2 – Assemble legs
Take the 3x legs and insert them into the socket that fits each one of them on each side by aligning the screw sockets in each leg to the screw hole on each side of the assembly, and then secure them with 1x M3x5 screw in each leg.
Step 3 – Assemble PSU rest
Secure the squared PSU rest to the bottom of the big leg designated for mounting the PSU.
You need to secure the PSU rest to the leg with 4x M3x5 screws.
Step 4 – Assemble GPU bracket
Add the GPU bracket to the assembly by inserting it into the 2 holes on one of the long sides.
(Note that the holes on top of GPU-bracket have to “point” inside the assembly. Otherwise, they won’t fit with the mounting holes on your GPU), then secure the GPU-bracket with 2x M3x5 screws from underneath the assembly.
Step 5 – Install Power switch
Insert the included Power switch into the hole on the bottom-right corner of the PSU leg.
Step 6 – Install Computer hardware
Now mount and secure the motherboard, PSU and SSDs (Optionally) to the assembly with the remaining screws.
Final Assembly
Verify that all screws are tightened properly and that cables are routed safely.
Cable management and hardware configuration may vary depending on components used.
