2. Setup and Installation
Before beginning installation, ensure you have all necessary components and tools. Work on a clean, static-free surface.
2.1 Opening the Case
Carefully remove the tempered glass side panel by unscrewing the thumb screws located at the rear of the case. Place the panel on a soft, flat surface to prevent scratches.
2.2 Motherboard Installation
The Kyanite case supports ATX, Micro ATX, and Mini ITX motherboards. Install the necessary standoffs for your motherboard form factor. Carefully align your motherboard with the standoffs and I/O shield, then secure it with screws. Ensure all screws are tightened appropriately, but do not overtighten.

2.3 Power Supply Unit (PSU) Installation
The case features a bottom-mount PSU design. Slide your ATX power supply into the designated compartment at the bottom rear of the case and secure it with screws from the exterior. Ensure the PSU fan faces downwards for optimal cooling if the case has a bottom vent.
2.4 Storage Drive Installation
The Kyanite case provides 4 internal bays compatible with 2.5" and 3.5" storage drives. Mount your SSDs or HDDs into the drive cages or designated mounting points and secure them with the appropriate screws.
2.5 Graphics Card (VGA) and Expansion Card Installation
Remove the necessary expansion slot covers at the rear of the case. Insert your graphics card (VGA) or other expansion cards into the PCIe slots on your motherboard and secure them with screws. The case supports VGA cards up to 295mm in length.
2.6 CPU Cooler Installation
Install your CPU cooler according to its specific instructions. The case accommodates CPU coolers up to 160mm in height.
2.7 Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to manage cables. This improves airflow and aesthetics. Connect all power cables from the PSU to your components and all data cables to your storage drives and motherboard.
