Custom 24-carat gold mini PC costs around $1.7 million, weighs nearly 29 pounds for up to 50% faster heat transfer

A chrysophile has ordered a special edition mini PC with a pure 24-carat gold passive chassis reports Fanless Tech. It’s a premium custom version of the ~5-inch (120 x 120 x 120mm) Kubb Fanless PC, but costing around $1.7 million with its opulent gold chassis. As well as its choice of materials pumping up price, this mini PC’s weight has increased from its default 4.6 to 28.7 pounds (2.1kg to 13kg). But as a bonus, which probably still doesn’t make it worth it for most folks, gold has significantly better thermal conductivity than aluminum.

In its social media post, Fanless Tech calls the Kubb Fanless in gold a “cooling marvel.” Its news post on the topic elaborates on this claim, explaining that the thermal conductivity of gold is “about 30% to 50% faster than aluminum.” That might help its Core Ultra chip perform a bit better, all else being equal. However the sacrifice to portability, as this compact gold PC is over 6x heavier, could be a major drawback. As well as the price.

We looked up the thermal conductivity of aluminum and gold, as well as some other common materials. The chart below could be useful for your own passive computing projects.

In contrast to its gilded construction, this mini PC’s specs are very modest. Standard configurations of the Kubb Fanless are as follows:

• Intel Core Ultra 5 225H, or Intel Core Ultra X7 358H, or AMD Ryzen AI 5 340
• 16GB DDR5, up to 128GB
• 1TB M.2 NVMe SSD, optional second M.2 SSD
• Intel: 1x USB 3.2 (Type A), 1x USB 3.2 (Type-C, DP1.4a), 1x USB4/Thunderbolt 4 (Type-C, DP 2.1), Wi-Fi 7, Bluetooth 5.4
• AMD: 1x USB 3.2 Gen2 (Type A), 2x USB4 (Type-C, DP 1.4a), Wi-Fi 6, Bluetooth 5.3
• Side ports: 2x Port RJ45, 2x HDMI 2.1 TMDS, 2x USB 3.2 Gen 2 (Type A)
• 19V DC, 6.32A, 120W power adapter (100–240V AC)
• Windows 11 Pro
• 3 years guarantee

Kubb Fanless mini PCs are usually made from aluminum, and finished in graphite, blue, or bronze. With an Intel Core Ultra 5 225H at their heart, all those colors are all listed at €1,595 ($1,822) at Kubb.eu, but there is no stock. At that kind of price, the Arctic Senza AI 370 we tested earlier in the year looks like it would be a knockout passive computing competitor. We aren’t sure if Arctic would accept the 24 carat gold chassis special order, and the Senza is designed for discrete under-desk-mounted silence.

We previously reported on the fanless Kubb Mini range of 3 x 3 x 3-inch mini PCs which packed Intel Twin Lake chips, came in cute/bright color finishes, and were priced around $500 (€430).
