MintBox3 is a high-end fanless SFF Linux desktop with Compulab and Linux Mint bring to Australia the MintBox3 – the 5th generation of the popular MintBox product line of ready-to-use Linux Mint fanless PCs.

MintBox3 Pro model is powered by an 8-core Intel® Core™ i9-9900K Processor and Nvidia GTX 1660 Ti, both passively cooled using Compulab’s Natural Airflow technology. It ships with the latest Linux Mint 19.3 “Tricia” Cinnamon pre-installed.

Compulab provides 5 year warranty on MintBox3. Of each MintBox3 sold, 5% is donated to Linux Mint.

Best-in-class user experience

MintBox3 is a version of Compulab Airtop3 customized to deliver the best possible desktop Linux experience. High-end CPU coupled with a powerful discrete GPU, high memory capacity and fast NVMe SSD ensure quick loading and excellent responsiveness of the user-friendly Cinnamon desktop environment.

The small footprint of MintBox3, silent cooling, aesthetic all-metal industrial design and accessible I/O ports allow for a convenient, distraction-free use.

The high performance of MintBox3 is beneficial for productivity of developers and artists where high computational workloads and graphics intensive tasks are involved.

Open and user-friendly industrial design

The most unique feature of MintBox3 is its thermal design. MintBox3 can dissipate up to 300W from its 7.5 liter chassis without fans or any moving parts, by natural airflow resulting from the waste heat of the CPU and the GPU. Natural airflow cooling is silent, extremely reliable and requires no periodic cleaning or any other maintenance.

MintBox3 has an unusually rich set of features for a mini desktop – including up to 128 GB RAM, 6 storage devices, up to 7 4K displays, dual LAN, Wi-Fi, 9 USB ports, audio jacks on front and back and serial ports.

The user is welcome to open MintBox3 to add, remove and upgrade RAM, storage, add-on cards and even the graphics card. Opening MintBox3 is tool-free:

  • Press the top-bar and the clamshell door opens, revealing the RAM and disk cartridge

  • Pull the disk cartridge ejector to expose the NVMe and Wi-Fi adapter.

Installing devices in MintBox3 does not void the 5 year warranty.

MintBox3 ships ready-to-use with Linux Mint 19.3 “Tricia” Cinnamon pre-installed and no bloatware. User can easily install Mate edition, another Linux distribution, Windows 10 or another operating system.

Compulab and the Linux Mint team have spent long time optimizing the MintBox3 derivative of Airtop3 for the best user experience. Among the changes –

  • Extensive testing of Linux Mint 19.3 on MintBox3 to ensure full compatibility

  • Full Linux Mint branding including embossed and diamond cut Linux Mint logo as part of the housing, Linux Mint boot image and logo of the integrated OLED display

  • Qualifying a single thin 330W power supply eliminating the need for dual power supplies

  • Tuning BIOS and drivers for optimal acoustic “coil whine” mitigation to ensure quiet user experience

  • Reconfiguring audio output to default to front earphones and MIC jacks

  • Redesigned packaging for superior shock absorption during transport


MintBox3 is based on the industrial-grade PC Airtop3. The motherboard is custom designed using embedded-grade components. The housing is all-aluminium. MintBox3 is passively cooled with no moving parts and requires no maintenance.

MintBox3 ships with a 5 year warrant
