The Fastcalc X8B is a new mini PC that has surfaced on Amazon in Germany, though broad worldwide availability does not appear to be established yet. It is likely a rebranded OEM device rather than a ground-up new design. The model starts at €700 for a configuration with 8 GB of RAM and a 256 GB SSD—a fairly minimal setup, though not necessarily a deal-breaker given its expansion options.
The system is clearly tailored for network applications like firewalls or industrial deployments, featuring eight 2.5 GbE ports. However, it is by no means limited to server room duties. With HDMI, DisplayPort, USB Type-C, four USB 3.2 ports, it offers all the connectivity needed for standard desktop use. Broad operating system support is expected, as the Intel Core Ultra 5 125U uses a standard architecture.
Thanks to its fanless design and prominent cooling fins, the X8B operates silently and is well-suited for demanding industrial environments such as factory floors. Hardware maintenance and upgrades are straightforward: its two DDR5 slots accept up to 64 GB of RAM, and the preinstalled M.2 2280 SSD can be easily swapped out.

I have been active as a journalist for over 10 years, most of it in the field of technology. I worked for Tom’s Hardware and ComputerBase, among others, and have been working for Notebookcheck since 2017. My current focus is particularly on mini PCs and single-board computers such as the Raspberry Pi – so in other words, compact systems with a lot of potential. In addition, I have a soft spot for all kinds of wearables, especially smartwatches. My main profession is as a laboratory engineer, which is why neither scientific contexts nor the interpretation of complex measurements are foreign to me.
