Who it fits
Good fit for
This mini PC suits home office workers and light gamers who need reliable multitasking. The strong CPU handles virtual machines and large media files efficiently. Dual Ethernet ports make it ideal for network-attached storage or server tasks. Users who want to connect two 4K displays will appreciate the dual HDMI 2.1 outputs. The quiet cooling system ensures it stays unobtrusive during long work sessions or media playback.
Who should skip it
You should look elsewhere if you require high-end gaming performance. The integrated Radeon 780M graphics cannot match dedicated video cards for demanding titles. Heavy 3D rendering or professional video editing workflows may exceed its capabilities. If you need more than 16GB of RAM pre-installed, this specific configuration may limit you. Users requiring Thunderbolt 4 compatibility should note this unit offers USB4 instead, which has different protocol support.
Verdict: The KAMRUI AM21 delivers solid multi-core performance and versatile connectivity for general use and light gaming. It is a practical choice for users prioritizing CPU power and expandability in a compact chassis.

Design and build quality
The KAMRUI AM21 uses an all-copper cooling assembly to manage heat. According to the listing, this system includes three heat pipes, copper fins, and a high-speed silent fan. Dual air intakes help move air through the chassis. This design choice means the unit can handle prolonged heavy loads without throttling. The manufacturer states the maximum noise level is 41.0dB under full load. You can place this PC in a quiet office or studio environment without significant distraction. The passive and active cooling components are integrated into a compact frame.
The physical dimensions are not explicitly listed in the provided data, but the model is described as a mini PC. You get two 1Gbps Ethernet ports, which is unusual for this form factor. This dual-port layout supports network bonding or separate network segments. The rear panel includes two HDMI 2.1 outputs for dual monitor setups. You also have one USB4 Type-C port and one full-function USB 3.2 Gen2 Type-C port. Both Type-C ports support DisplayPort 1.4 and 100W PD input. This allows you to connect high-resolution displays while charging a laptop or other device.
The chassis finish is not detailed in the specifications. However, the port selection suggests a focus on connectivity over aesthetic flair. You can connect projectors, commercial equipment, or surveillance monitors directly. The presence of audio in/out jacks adds versatility for multimedia use. The build prioritizes thermal efficiency and interface abundance. You get a robust cooling solution and extensive I/O options in a small footprint.
Setup and everyday use
Setting up this mini PC involves connecting power and displays to its rear panel. You use the included DC port for power. For video output, you have two HDMI 2.1 ports that support 4K at 60Hz. You can also use the USB4 Type-C port for display output, which supports 8K at 60Hz or 4K at 120Hz. This port also handles data at 40Gbps and provides 100W PD input. The second Type-C port offers 10Gbps data, 4K at 60Hz display output, and 100W PD input. You can connect two monitors simultaneously using the HDMI ports. For networking, you have two 1Gbps RJ45 Ethernet ports, allowing for stable wired connections or link aggregation. Audio connects via the standard in/out jack. Daily use relies on the Ryzen 7 8745HS processor and Radeon 780M graphics. The eight-core CPU handles multitasking and content creation efficiently. The integrated graphics support 1080p gaming and 8K video playback with AV1 hardware decoding. You get 16GB of DDR5 RAM and a 512GB PCIe 4.0 SSD for fast boot times. The system uses an all-copper cooling assembly to manage heat. It maintains a maximum noise level of 41.0dB under full load. This makes it suitable for 24/7 operation in offices or studios. You can expand storage to 4TB using dual M.2 slots. You can also upgrade RAM up to 96GB. The versatile ports allow you to connect projectors and commercial equipment easily. This setup supports office workstations and surveillance applications.
Before you buy this mini pc
You should verify your display requirements before purchasing. This unit includes two HDMI 2.1 ports and one USB4 port with DisplayPort 1.4 support. If you need more than two screens, you must check if your specific monitor configuration works with these outputs. The USB4 port supports 8K video at 60Hz, which is useful for high-resolution displays. You will also need to consider storage expansion. While it comes with a 512GB PCIe 4.0 SSD, you can add a second drive if needed. The system supports RAM upgrades up to 96GB, so you can increase memory later if your workload demands it. Compared to other options in the 1 Mini PCs & Small Form Factor Computers guide, this model focuses on raw processing power and connectivity. It is ideal if you need strong multi-core performance without a dedicated graphics card. You should also ensure your workspace can accommodate its size and cooling needs. The all-copper cooling system requires adequate airflow to maintain its quiet operation during heavy loads. Regularly dusting the air intakes will help keep noise levels low and performance steady over time.
Check before you buy
- Check if your monitors work with HDMI 2.1 and USB4 outputs.
- Verify you have space for the all-copper cooling system airflow.
- Confirm if 512GB storage is enough or if you need expansion.
- Ensure your power outlet is near the DC port location.
