> Minisforum likes to turn itself off every couple of weeks, not sure why yet

AFAICT, the answer is "because Minisforum". I don't know if they have a design principle that they should run their systems near the edge of the thermal envelope or what, but Minisforum is the only brand I've had consistent trouble with stability on. My last one got to where it stopped booting altogether, just looped. Since then I've written off Minisforum as a brand, just not worth the hassle.
