Maybe it's time to leave the world of big desktops and just use a miniPC I have had sitting on the shelf for the last 6 years.
All the power of my current rig has sort of been wasted anyway. I have reduced my RAM usage to less than 2G at the peak usage and my CPUs never spike above 30% on one of the 8 cores. (Technically sometimes I hit a bug where it maxes out 2 cores, but I won't have to worry about that since I won't be using KDE anymore for the main desktop)
