I grabbed an ASUS E210 about a year ago and it's doing great with Linux on it. It's fanless, with an 11.6" display, 4G of ram, a 1.1 Ghz celeron, and 64G of storage. You can get one dirt cheap as an ex display model. I don't know if it's still up, but there was a surprisingly good repair manual for it on the ASUS web site, showing in detail how to install an m.2 storage device, so I souped it up with an additional 8TB of storage, which I'm using for jellyfin, immich, calibre, and paperless-ngx. It will just about manage to run a virtualbox vm if you need to do any windows stuff.
