Key Considerations

• PSU compatibility: Flex ATX is most common. Some cases support Mean Well LOP-300, ATX, or SFX. Check before printing.
• Heatsink mod required: Most cases assume you have opened the fin stack on the stock heatsink. See Cooling Guide.
• Nylon washers: 4x M3 nylon washers under heatsink screws prevent shorting. See Cooling Guide > CRITICAL.
• Filament: PETG or PETG-CF recommended for heat resistance. PLA may deform near the VRM/backplate area.
• Threaded inserts: Many designs require M3 heat-set inserts.
• WIP designs: Some threads are early concepts. Verify availability before starting a print.
