Tiny 3-inch cube PCs bring a splash of color to the passive PC market with red, orange, green and blue options — Intel Twin Lake-powered Kubb Mini PCs start at $500

Passive PCs are great for those who like to keep background noise to a minimum in their work environments. Traditionally, passive designs have leaned towards the adoption of ‘quiet’ visual designs, too. But that doesn’t have to be the case, as the new Kubb Mini range demonstrates (h/t Fanless Tech). These compact 3-inch cubes are priced at $500 (€430) and come in some rather vivid red, orange, green, and blue options - as well as staid old black or white.

Passive cooling of these PCs isn’t the trickiest, as the CPU options have rather low TDPs. For example, the Intel Twin Lake N150 with 4C/4T and a top speed of 3.6 GHz has just a 6W processor base power. The Core i3 N300 CPU with 8C/8T and a top speed of 3.8 GHz has a slightly higher TDP at 7W. Both CPUs are fabbed at Intel 7 and have 6MB of Intel Smart Cache on board. Neither should be a challenge to a small passive cooling setup.

The $500 (€430) configuration of the Kubb Mini comes with the weaker N150 processor, but it isn’t barebones. The processor is supported by 16GB LPDDR5-4800 RAM, a 256GB NVMe SSD, and Windows 11 Pro comes pre-installed. Opting for the Core i3 N300 CPU, with all else remaining equal, adds $105 (€90) to the checkout price. Neither config can add more than 16GB of RAM, but 512GB and 1TB storage options can be had for more of your hard-earned cash.

You don’t get oodles of connectivity, which isn’t a big surprise. What you do get is: Realtek RTL8111H 1 GbE, Intel Wi-Fi 6 AX201 + Bluetooth 5.2, 2 × USB 3.2, 2 × HDMI 2.0, 1 × USB 3.2, and 1 × audio 3.5mm. It looks like there is a barrel jack for the 12 V DC power adapter around the back, but the device can also be powered by one of its precious USB-C ports.

Kubb envisions users buying this 3-inch (8cm) square PC for “office tasks, management, accounting or web browsing.” It also heralds the Mini as a great, silent, thin client that uses significantly less power than a traditional desktop PC. Perhaps more appealing to our audience, Kubb reckons the Mini would also be a good choice for “entertainment and retrogaming for the whole family,” plugged into the living room TV while not becoming an eyesore.

Kubb also makes more powerful (larger) fanless designs and its stables, dominated by cube-like solutions, feature wood- and leather-cased PCs, too.

    The price is too high with Wildcat Lake around the corner.

    I can't believe it costs $500... Even for a fanless, that's really expensive
    It doesn't have Wi-Fi 6e, nor does it have 2.5Gbe
    MeLE and Minix sell a similar fanless N150 16GB/512GB for less.

    It's like what... $10 for primer and spray paint

    Being a small French company is probably the reason: https://kubb.eu/en/contact-us
    They also sell systems with fans. Their Strix Halo 395 box with 128 GB LPDDR5X is €3,690.00: https://kubb.eu/en/content/28-kubb-octo-concentrated-intelligence-unleashed-performance
    I think Wildcat Lake could be used fanless with a 10W cTDP and good enough heatsink. Getting expensive Alder Lake-N boxes this late in its lifespan and during the memory/storage crisis isn't a good idea if you can avoid it.

    My tablet has more power than that thing.

    My eyes are not what they used to be and I haven't had coffee but even with that handicap I can tell there is no barrel jack on the back or anywhere on this computer.

    While yes it is kinda confusing to read a spec table without coffee, doing a double take confirmed that it is powered only over type-C. An AC/DC external power supply adapter is included that does 12V over USB-C, good for up to 30W of power. The datasheet on the website makes this fact more clear, that it supplies 12V and 2.5A over USB-C.

    And yes 12v is part of the USB-C PD spec, although there is nothing indicating that the power supply or the computer is PD compliant.

    It seems to be way too expensive as all heck, I've seen mini PCs from some Chinese brands being cheaper with similar specs, and even cheaper if passive cooling isn't a requirement...

    But my god, it's so cute!
