Desktop OSs tend to bloat a bit over time. I recently switched from Gnome to XFCE on my old HP mini-PC and it has made it much snappier to use. It's great having these options to keep the older hardware from Landfill. In the dept where I work we try to keep PCs going rather than the standard option which is to dispose of after 3 years. This often involves upgrading RAM and replacing HDDs with SSDs. If only more people would do this it would take some pressure off the climate and Earth's resources, but unfortunately it's easier for people to throw away and replace. In many workplaces one is encouraged to spend money, because if you don't you don't get the same budgets next year. Crazy stuff.
