3.1 Unpacking and Preparation
Carefully remove the chassis from its packaging. Inspect for any damage that may have occurred during shipping. Place the chassis on a stable, flat surface. Remove the side tempered glass panel by unscrewing the thumb screws and gently pulling the panel away.
3.2 Component Compatibility Overview
Before installing components, review the maximum supported dimensions for your hardware to ensure compatibility with the ZOFOS ULTRA case.

3.3 Motherboard Installation
Install the necessary standoffs for your motherboard form factor (E-ATX, ATX, M-ATX, or ITX). Carefully place your motherboard onto the standoffs, aligning the screw holes. Secure the motherboard with the provided screws.
3.4 Power Supply Unit (PSU) Installation
Mount your ATX power supply into the designated PSU bay. Ensure the PSU fan faces the correct direction for optimal airflow, typically downwards if there is a filtered vent, or upwards if drawing air from inside the case. Secure the PSU with screws from the rear of the chassis.
3.5 Storage Device Installation
The ZOFOS ULTRA offers flexible storage options. Utilize the drive bay brackets for installing 3.5-inch HDDs or 2.5-inch SSDs. The case also supports a 5.25-inch Optical Disc Drive (ODD).

3.6 Cooling System Installation (Fans & Radiators)
The ZOFOS ULTRA supports extensive air and liquid cooling configurations. Install fans according to your cooling needs. The case can accommodate up to 15 x 120mm fans across various locations.


For liquid cooling, the case supports radiators in multiple positions:

3.8 Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to manage cables effectively. Proper cable management improves airflow and aesthetics.
4. Operating Instructions
4.1 Powering On Your System
Once all components are installed and cables are connected, close the side panel. Connect your monitor, keyboard, mouse, and power cable. Press the power button on the front I/O panel to start your system.
4.2 ARGB Lighting Control
The ZOFOS ULTRA features integrated ARGB lighting on the front panel. This lighting can be controlled directly from the front panel LED button, allowing you to cycle through various lighting effects and colors without additional software.

5. Maintenance
5.1 Cleaning Dust Filters
The ZOFOS ULTRA is equipped with magnetic dust filters for easy removal and cleaning. Regularly clean these filters to maintain optimal airflow and prevent dust buildup inside your PC. Simply remove the filters, clean them with water or a soft brush, and reattach them once dry.

5.2 General Cleaning
Use a soft, dry cloth to wipe down the exterior of the case. For tempered glass panels, use a glass cleaner and a microfiber cloth to avoid streaks. Avoid using abrasive cleaners or solvents.
6. Troubleshooting
- System Not Powering On: Double-check all power connections, including the 24-pin ATX, 8-pin CPU, and GPU power cables. Ensure the PSU switch is in the 'ON' position.
- Fans Not Spinning/ARGB Not Working: Verify that all fan and ARGB headers are correctly connected to the motherboard or a dedicated controller. Check the front panel ARGB control button.
- No Display Output: Ensure your monitor cable is connected to the graphics card (not the motherboard integrated graphics, unless you are using integrated graphics). Reseat the graphics card and RAM modules.
- Overheating Issues: Confirm all fans are installed correctly and spinning. Clean dust filters and ensure proper airflow within the case. Check CPU cooler and GPU cooler mounting.
