Gmktec has officially introduced the new NucBox M3 Pro Mini PC, a small yet capable machine designed for office work, multitasking, media consumption, and home server setups.

The new model comes powered by Intel’s Core i5-13500H processor and offers support for up to three 4K displays, making it an attractive option for professionals and productivity-focused users. Despite its compact size, the system includes expandable storage, dual Ethernet ports, and modern connectivity options.
Gmktec NucBox M3 Pro Specs and Features
Intel Core i5-13500H Processor
At the heart of the NucBox M3 Pro is the Intel Core i5-13500H processor. This 12-core, 16-thread chip is commonly found in mid-range laptops and delivers reliable performance for everyday computing tasks. Whether users are handling spreadsheets, web browsing, content streaming, or multitasking between several applications, the processor is capable of maintaining smooth performance.
The integrated Intel Iris Xe graphics handles standard graphics workloads comfortably. While this mini PC is not aimed at hardcore gaming, it can easily manage 4K video playback, office applications, online meetings, and multi-monitor productivity tasks.
Compact Design with Efficient Cooling

One of the key highlights of the NucBox M3 Pro is its lightweight and compact body. Weighing around 480 grams, the mini PC can fit neatly on a desk or even behind a monitor using its VESA mount support.
To maintain stable performance during long working sessions, Gmktec has included a cooling system featuring a single fan and copper heat pipe setup. Air vents on both sides help improve airflow and reduce internal temperatures.
Upgradeable RAM and Storage
Even though the device is compact, users still get plenty of upgrade flexibility. The mini PC includes two SO-DIMM slots supporting up to 64GB DDR4-3200 memory. Gmktec has chosen DDR4 instead of DDR5 to keep pricing more affordable while still offering solid performance for office and productivity tasks.
Storage expansion is another strong point of the NucBox M3 Pro. The system includes:
- One M.2 2280 PCIe 4.0 NVMe slot supporting SSDs up to 8TB
- One additional M.2 2242 slot supporting SATA or PCIe 3.0 drives
This setup allows users to configure the mini PC for both speed and large-capacity storage needs.
Triple 4K Display Support
For users who work with multiple screens, the NucBox M3 Pro offers support for up to three 4K displays simultaneously. This makes it suitable for multitasking, trading setups, content monitoring, or professional office use.
The available display outputs include:
- Two HDMI 2.0 ports
- One USB-C port with display support
With three monitors connected, users can create a more productive desktop environment without needing a larger traditional PC tower.
Modern Connectivity Options
Gmktec has included a useful mix of front and rear ports for everyday use.
On the front, the mini PC features:
- Two USB-A 3.2 Gen 2 ports
- One USB-C port
- One 3.5mm headphone jack
The rear panel includes:
- Two HDMI 2.0 ports
- Two USB-A 3.2 Gen 1 ports
- Dual 2.5G Ethernet ports
The dual Ethernet setup makes the system especially appealing for networking enthusiasts, home server users, or people planning to use the device as a custom router.
Wireless connectivity includes Wi-Fi 6 and Bluetooth 5.2 for faster wireless networking and accessory pairing.
