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

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
oEnsure 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
oManually 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
