I think it will depend on where you are at in the 'programmer' journey. For me, while it was still an exciting hobby decades ago, I used to collect PCs and consoles, keyboards and peripherals etc. just to tinker with them and experiment.

Then, as programming became more and more of a 'day job' and not a fun side project, I found myself getting rid of the clutter of obsolete equipment around the place. 35 years later, I am happy with just a basic iMac as my main development machine, and a Lenovo laptop as my Windows/backup development machine. That is it. No more multi screen setups or fancy keyboards & mice even - just stock standard stuff to get the job done so I can spend energy on my passion projects.
