I use my machines mostly for development and don’t need a powerful GPU, just lots of CPU and RAM, and fast storage. I just bought two HP EliteDesk 800 G5 with an i7-9700K and an i9-9900K. Those are 95W TDP processors in an absolutely tiny 1 liter chassis that’s a marvel of engineering, replacing the already fairly small HP Z200 and Z230 SFF workstations I used previously. The second one (I haven’t received it yet) even has dual M.2 NVMe slots.
Here is Geekbench on the i7-9700K, fastest machine I own:
