Old “Cannot be upgraded to Windows 11” Laptop Computer

I’m looking for an old but still working, laptop with a view to installing Linux for a specific project
Condition not important, just hopefully not too expensive.
Minumum spec seems to be very modest – something like this…

• CPU: 1 GHz Dual Core – Intel/AMD 64-bit processor
• RAM: 2-4 GB
• Storage: 100 GB
• Display: 1024 × 768 resolution
