Tiny 3-inch cube PCs bring a splash of color to the passive PC market

At a glance:

• Kubb launches the Mini range of 3-inch (8cm) fanless cube PCs.
• Powered by Intel Twin Lake processors with TDPs as low as 6W.
• Available in vivid colors including red, orange, green, and blue.

A colorful approach to silent computing

Passive PCs have long been the preferred choice for users seeking a silent work environment, but they have traditionally suffered from a visual identity crisis. Most fanless designs lean toward a "quiet" or "stealth" aesthetic, often utilizing muted grays, blacks, or whites to blend into the background. The new Kubb Mini range aims to disrupt this trend by pairing silent, fanless operation with a vibrant palette of aluminum exteriors.

These compact 3-inch (8cm) cubes are designed to be more than just functional tools; they are intended to be stylistic additions to a workspace or living room. In addition to the standard black and white options, Kubb is offering the Mini in vivid shades of red, orange, green, and blue. This move signals a shift in the mini PC market, where hardware is increasingly being treated as a lifestyle accessory rather than just a piece of beige office equipment.

Intel Twin Lake architecture and thermal efficiency

The ability to maintain a completely passive, fanless cooling system in such a small footprint is made possible by the low Thermal Design Power (TDP) of the selected Intel processors. The Kubb Mini utilizes the Intel Twin Lake architecture, which is specifically optimized for efficiency. Because these chips generate minimal heat, the compact aluminum chassis can act as a highly effective heat sink without the need for moving parts.

Kubb offers two primary CPU configurations for the Mini series:

• Intel Twin Lake N150: 4 cores, 4 threads, 3.6 GHz top speed, and a 6W processor base power.
• Intel Core i3 N300: 8 cores, 8 threads, 3.8 GHz top speed, and a 7W TDP.

Both processors are manufactured using the Intel 7 process and include 6MB of Intel Smart Cache. This low-wattage approach ensures that the device remains silent during heavy workloads while consuming significantly less power than a traditional desktop PC.

Pricing, configurations, and connectivity

Kubb has positioned the Mini as an accessible entry point into the premium fanless market, with base models starting at $500 (€430). The entry-level configuration features the Intel N150 processor paired with 16GB of LPDDR5-4800 RAM and a 256GB NVMe SSD, with Windows 11 Pro pre-installed. Users looking for more processing headroom can upgrade to the Core i3 N300 for an additional $105 (€90).

While memory is capped at 16GB for these specific models, users can customize their storage capacity, with options available for 512GB and 1TB NVMe SSDs. Connectivity is streamlined to fit the compact form factor, providing the essentials for a modern workstation or media center:

• 1 × Realtek RTL8111H 1 GbE (Ethernet)
• Intel Wi-Fi 6 AX201 + Bluetooth 5.2
• 2 × USB 3.2 ports
• 1 × USB 3.2 port
• 2 × HDMI 2.0 ports
• 1 × 3.5mm audio jack

Power delivery is also flexible; the device features a standard 12V DC barrel jack on the rear, but it can also be powered via one of its USB-C ports, making it highly adaptable for various mounting or cable management scenarios.

Targeted use cases for the Kubb Mini

Kubb is targeting a diverse range of users, from professional environments to home entertainment setups. For the office, the Mini is marketed as an ideal solution for management tasks, accounting, and general web browsing where silence is a priority. Its small footprint and low power draw also make it an excellent candidate for a thin client in enterprise environments.

Beyond the office, the company envisions the Mini as a versatile media hub. Its silent operation and compact size make it a great choice for entertainment and retrogaming, allowing it to be plugged into a living room TV without becoming a bulky or noisy eyesore. This versatility is part of a broader product strategy from Kubb, which also produces larger fanless designs and premium PC cases featuring wood and leather finishes.
