I have a Dell Latitude C600 sitting right next to me - I use it to run old legacy apps. It only has a 80 MB HDD and miniscule memory; once it finds the wifi router it takes ten minutes to load a web page, but it gets the job done and can run old DOS-based apps without an emulator. I’m an old Dell repair tech, so I get a kick out of other people’s trash.
I have 3 Dell Optiplex 780s [one for each of two locations and a spare] that have been updated with SSDs [they were surplus hospital data entry devices sold at ~$15 w/o a HD].
All running Linux and are able to surf just fine @ 1920x1080.
