I work on a desktop, but as a backup I have bought a refurbished Dell Latitude, there are a lot of decent ones for €250 on eBay. Put Linux on it, it’s good enough for most workloads.
I just hope my top shelf 2020-era desktop doesn’t die on me because it would get very expensive to get a new build these days.
I did exactly this and suggest it. Used Dell Latitude (the one I got is one from 2019 - model 5300). I put Linux Mint Debian Edition (https://linuxmint.com/download_lmde.php) on it. Works absolutely great.
Small Dell Optiplexes are good for desktop computers.
I got an old hp elitedesk off of eBay, I don’t remember the cpu but it has 8 gig of ram and an ssd. Ubuntu+dokku and it runs all my self hosted stuff.

I could probably sell my gaming rig (12900K, 64GB of DDR5, 4TB NVME, RTX 3090) for more today than what I built it for about 4 years ago, it's absurd. I won't, of course, because it's still glorious for 4K gaming even today. In retrospect, $5000 very well spent.
