Kind of a “self-flex”, but one of the “#1 container” I mentioned in the OP, cmatrix (should have said image, I was way too sleepy when I posted this, but eh) uses less than 1% of the CPU and exactly 486kb of RAM (and that is on a RPI 4), so yep… pretty sure any PC (and I -REALLY meant to say ANY) will have 0 issues running those tiny, “waste of resources” apps. :^)
