Another source of cheap compute power is broken laptops on fleaBay. Particularly the fleet and "slightly upscale" models still have respectable horsepower... 6th-8th gen i5-i7, DDR3/DDR4; in some cases even NVMe
and SATA3... and can be had very cheap if the screen or shell is borked; just remove the display and print a stand for the lower half or a bracket to hang it off the VESA mount of your monitor.
Or if you're
really feeling froggy, design/print a case for the whole thing. Many of them now have MBs that are <220mm x 220mm (most common size of small cheap 3DP build plate) including cooling solution.
Another nice thing aboot laptop MBs is they almost
always include a license burned into the BIOS that's good for Win7-Win10. Obvi, not with ChromeBooks, but hey... you should know better.

Reuse is the highest form of recycling.
Yes, I've got nothing against SBCs and the Raspberry Pi in particular, and there are some things where they are an ideal fit, but I do think it's something of a bandwagon that people jump on without thinking about their needs, or being aware of the alternatives, in the form of NUCs, thin clients and laptops etc.
The first time I came across the Raspberry Pi when I found someone I knew was using one to monitor the temperature and humidity of his bee hives, about 6 years back. The sensors were connected through USB. The R Pi was £30 and the case was £5 and the PSU probably another £5. It really didn't need any computing power. A carefully chosen thin client (dirt cheap, because the CPU isn't fast enough for a pleasant desktop computing experience) would have been a cheaper and neater solution, and with about the same power consumption.
Something I don't like about the Raspberry Pi is the SD card and SATA HDD connected through USB, although I must say, it has caused me no particular problems.
