Totally true. I have a trusty old (like 2016 era) X99 setup that I use for 1.2TB of time series data hosted in a timescaledb PostGIS database. I can fetch all the data I need quickly to crunch on another local machine, and max out my aging network gear to experiment with different model training scenarios. It cost me ~$500 to build the machine, and it stays off when I'm not using it.

Much easier obviously dealing with a dataset that doesn't change, but doing the same in the cloud would just be throwing money away.
