I have been running for years a small Linux box for various activities, such as recovering hard drives with bad sectors, hosting local source repositories, running a local DNS server, and so on. My original Linux installation went through many hardware upgrades over the years and eventually ran into end-of-life for the 32-bit Linux kernel. The time my Linux installation needed a bigger box.
Most of my Linux tasks are not CPU-intensive, so in the past I would recycle old hardware, but this time I decided that switching to 64-bit hardware deserves a quality upgrade and started looking for small PCs with good connectivity options. After researching this for a bit, I thought CompuLab's Fitlet3 will serve as the new home for my Linux setup, but it did not work out quite as well as I hoped.
