3. Setup and Installation
Follow these steps for assembling your system within the TR100 Snow chassis.
3.1. Chassis Overview and Access
The TR100 features a modular design with removable panels for easy access during installation. The side panels are secured with magnets, while the top and bottom panels use spring-loaded captive screws.

3.2. Motherboard Installation (Mini-ITX)
- Remove the necessary side panels to access the motherboard tray.
- Install the Mini-ITX motherboard onto the designated standoffs. Secure it with screws.
3.3. Power Supply Unit (PSU) Installation
The TR100 supports SFX and SFX-L power supplies. It features a removable PSU bracket for easier installation.
- Attach your SFX or SFX-L PSU to the removable PSU bracket.
- Mount the bracket with the PSU into the chassis, securing it with screws.
3.4. Graphics Card (GPU) Installation
The chassis supports GPUs up to 360mm in length and 70mm in thickness. The removable PCIe bracket and included PCIe 4.0 riser cable simplify installation.

- Detach the rear PCIe panel.
- Connect the PCIe 4.0 riser cable to your motherboard's PCIe slot.
- Mount your GPU to the removable PCIe bracket and connect it to the riser cable.
- Slide the assembled GPU and bracket into the chassis and secure it. An integrated GPU brace provides additional support.
3.5. Cooling Solutions
The TR100 supports various cooling configurations:
- CPU Cooler: Up to 68mm in height.
- Radiator Support: Up to 280mm (max thickness 53mm) on the top bracket.
- Fan Support: Two 120mm/140mm fans on top.

3.6. Storage Installation
The TR100 supports up to two 2.5" SSDs, with one in each chamber.
3.7. Front I/O Ports
The front I/O panel provides convenient access to essential connections:
- Power button
- Reset button
- HD Audio (headphone and microphone jacks)
- 2 x USB 3.0 Type-A ports
- 1 x USB 3.2 Gen 2 Type-C port

4. Operating Guidelines
Once your system is fully assembled, ensure all cables are securely connected before powering on. The TR100 is designed for efficient airflow to maintain optimal component temperatures. Ensure adequate space around the chassis for proper ventilation.
4.1. Airflow Management
The chassis features well-designed cold air intakes and hot air exhausts to keep internal temperatures low. Proper fan configuration is crucial for maintaining system stability and longevity.
5. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your chassis and components.
5.1. Dust Protection and Cleaning
The TR100 is equipped with filters at the top, front, and side to protect your system from dust accumulation. Regularly clean these filters to maintain optimal airflow.

- Gently remove the dust filters from their respective locations.
- Clean the filters using compressed air or by rinsing them with water (ensure they are completely dry before reinstallation).
- Wipe down the exterior of the chassis with a soft, damp cloth. Avoid abrasive cleaners.
6. Troubleshooting
If you encounter issues during or after assembly, consider the following common troubleshooting steps:
- No Power: Ensure the PSU is properly connected to the wall outlet and the motherboard. Check all power cables (24-pin ATX, 8-pin CPU, PCIe power) are fully seated.
- No Display: Verify the monitor cable is connected to the graphics card (not the motherboard's integrated graphics ports, unless no discrete GPU is installed). Reseat the graphics card and RAM modules.
- PCIe Riser Cable Issues: The included PCIe 4.0 riser cable is designed for PCIe 4.0 compatibility. If you are using a newer PCIe 5.0 GPU and experience display issues, ensure your motherboard's BIOS is set to PCIe Gen 4 for the primary PCIe slot. Some PCIe 5.0 GPUs may not be fully backward compatible with PCIe 4.0 risers without this adjustment.
- Overheating: Check fan connections and orientation. Ensure dust filters are clean and not obstructing airflow. Verify CPU cooler installation.
- Loose Connections: Recheck all internal cables, including front panel connectors (power switch, reset switch, USB, audio).
