I mostly agree, and did the same with my second gen lab build - instead of shiny new NUCs like I had used round 1, I bought old off lease Dell Xeon boxes. SO MANY PROS -
The downsides can’t be denied though -
The same holds true for off-lease SFF stuff, Lenovo and the likes …
So while reuse/repurpose is absolutely of the utmost importance, no question - when it comes to technology and how quickly it advances and miniaturizes, a thorough and logical pros/cons list is often required.
I’d add another option though - if you do need what a Pi brings to the table - do you really need a shiny new Pi 5? Is it possible a used Pi 3 or Pi 4 would do the trick, and check the reuse box?
LOL!!
The original station was called “City TV”, they had a news program called “City Pulse”. In the late 90s/early 00s they launched a 24h news channel and called it “Cable Pulse 24”. At some point along the journey they shortened to that unfortunate name that I will now not ever be able to see and not laugh!!
