3. Setup and Installation
3.1 Unpacking and Inspection
Carefully remove the PC case from its packaging. Inspect the case for any signs of damage during transit. Ensure all accessories listed in the packing list are present. The case includes a plastic container with labeled bags for screws and zip ties for convenience.
3.2 Component Installation Guidelines
The D32 STD case is designed for efficient component installation. Follow these guidelines for optimal setup:
- Motherboard Installation: The case supports MINI-ITX and MICRO-ATX motherboards, including back-connect MICRO-ATX types. Ensure proper standoff alignment before securing the motherboard. For back-connect motherboards, the D32STD supports widths up to 207mm.
- Power Supply Unit (PSU) Installation: The case supports ATX, SFX-L, and SFX PSUs. A front power structure improves internal space utilization. For ATX PSUs, the recommended length varies based on GPU installation: 150mm (GPU in 1st PCI-E slot) or 170mm (GPU in 2nd PCI-E slot). A 14cm ATX PSU is generally easier to manage. Note: Internal power adapter cable is incompatible with 16A plug power supply.
- Graphics Card (GPU) Installation: The D32 STD supports graphics cards up to 365mm in length. The total clearance from the GPU backplane to the bottom is 94mm (1st PCI-E slot) or 73mm (2nd PCI-E slot). Adjust bottom fan installation based on GPU thickness and position.
- Cooling System Installation:
- Liquid Cooling: The top of the case supports 240mm AIO integrated liquid coolers. It can also accommodate a 30mm thick radiator with 30mm fans.
- Air Cooling: Compatible with high-performance dual tower air-cooled radiators with a height of up to 164mm (Intel CPU) or 163mm (AMD CPU).
- Fan Configuration:
- Top: 2 x 120mm or 2 x 140mm fans
- Bottom: 3 x 120mm or 2 x 140mm fans (forms a high flow intake channel)
- Rear: 1 x 120mm fan
- Storage Drive Installation: The case offers flexible storage options. It supports up to three 2.5" SSDs or a combination of two 2.5" SSDs and one 3.5" HDD.
- Cable Management: Utilize the provided zip ties and the case's internal routing options to manage cables effectively. For back-connect motherboards, ensure sufficient space for stiffer power supply cables.

4.2 Powering On
Press the power button located on the front panel to turn on your system. Ensure all cables are securely connected before powering on.
5. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your PC components.
- Dust Management: The case features a magnetic dust-proof net at the bottom. Regularly remove and clean this filter to prevent dust buildup inside the case, which can hinder airflow and component cooling.
- Cleaning Exterior: Use a soft, damp cloth to clean the exterior surfaces of the case. Avoid abrasive cleaners or solvents.
- Internal Cleaning: Periodically open the side panels and use compressed air to remove dust from internal components like fans, heatsinks, and circuit boards. Ensure the system is powered off and unplugged before performing internal cleaning.

6. Troubleshooting
This section addresses common issues you might encounter with your PC case.
6.1 System Not Powering On
- Check Power Connections: Ensure the PSU is properly connected to the wall outlet and the motherboard. Verify the power button cable from the case is correctly connected to the motherboard's front panel header.
- PSU Switch: Confirm the power switch on the PSU itself is in the "ON" position.
- Component Seating: Reseat the CPU, RAM, and GPU to ensure they are properly seated in their respective slots.
6.2 Overheating Issues
- Fan Configuration: Verify that all installed fans are spinning and configured for optimal airflow (e.g., intake at front/bottom, exhaust at top/rear).
- Dust Buildup: Clean all dust filters and internal components as described in the Maintenance section.
- Thermal Paste: Ensure CPU cooler has adequate thermal paste application.
6.3 USB Ports Not Functioning
- Front Panel Header: Check that the USB cables from the front I/O panel are securely connected to the correct headers on your motherboard.
- Driver Issues: Ensure your motherboard's chipset drivers are up to date.
