About a month ago, as I wrote at the time, I stopped using my 2012-vintage PC and once again started using the Minisforum UM250 small form factor PC you see at the left as my main PC. I had tried once before (back in May), but had been put off by the tendency of the Minisforum to crash or have strange graphical glitches. Second time was mostly a charm, however: the use of Kubuntu, rather than Arch or Manjaro, seems to have calmed the beast down to the point where it didn't crash and didn't do weird things with screen drawing.
I've accordingly been using the Minisforum UM250 very happily for a month or so. It doesn't have the memory heft of my old PC (that had 96GB of ECC RAM; this only has 16GB of ordinary stuff!) and its CPU, though a shiny (but not-so-new) AMD Ryzen 5 PRO 2500U, doesn't seem to have the raw power of my former Intel Xeon CPU E5-2680 v2: despite dating from 2013, its 20 threads seem to easily outpace the Minisforum's mere 8.
