• 14x 3M Bumpon adhesive rubber bumpers
• Hardware box; contents listed below. Quantities may vary.

| M3x0.5 5 mm countersunk screw

| M3x0.5 4 mm round head screw
| 6-32 6 mm round head screw
| M4x0.7 8 mm flat head screw

REQUIRED TOOLS

2 Phillips (PH2) screwdriver

CASE DISASSEMBLY

• Perform initial system assembly with all components and cables outside of the case
• Work on a soft, clean surface
• Once complete, disassemble the case to the following state
  

PSU

6-32 6 mm round head screw

MOTHERBOARD

• The CPU, CPU cooler, RAM, and storage should be installed onto the motherboard prior to this step

GRAPHICS CARD

M3x0.5 4 mm round head screw

MOTHERBOARD TRAY INSERTION

• Install the motherboard IO shield in the appropriate orientation
• Pay attention to the PCIe cable to prevent it from being caught on any edges
• Connect the graphics card’s power cable mid-way through insertion, and the remaining components’ power cables afterwards

SATA DRIVE

• Connect the SATA data and power cables to the storage drive and motherboard at this step

CLOSING THE CASE, RUBBER FOOT INSTALLATION

• Wipe the case surface to improve rubber foot adhesion
• Stick 4 adhesive rubber bumpers onto the bottom of the case according to the chosen orientation
• For quieter operation and increased internal clearances, mount the side panels using the adjacent mounting holes. The side panels will bend inwards at the center due to their concave shape, which can be partially mitigated by  inserting rubber bumpers between the case body and side panels

TROUBLESHOOTING

• Screw heads stripping
  o Ensure that you are using a #2 Phillips driver for the included screws. Using any other type of driver for the included screws can wear them down, making them difficult or impossible to remove.
  Replace damaged screws early

• System instability or no display output from the graphics card while using PCIe gen 4+ motherboard and graphics card with an older gen PCIe riser cable
  o Manually set PCI link speed in UEFI BIOS to match that of the PCIe riser cable (ex: gen 3). If there is no display output in UEFI BIOS, use onboard graphics (if available) or plug the graphics card directly into the PCIe slot without the cable to change this setting
