$#@! Intel NUCs were great small boxes with excellent Linux support (the only thing that doesn't work in Linux - custom fan control). In retrospect, NUCs were always the red-headed stepchild for Intel, last to get processor availability, so may that should have been expected.
System76 makes a similar sized unit called the Meerkat though I’m not sure how much it compares in other specs besides runs Linux and size. https://system76.com/desktops/meerkat
Any comparable brand with good Linux support?
