I’m the same. I want a new PC, but I refuse to buy windows 10.
Some time ago last I looked were lots of choices of Win7 etc
Any seller of, as Amazon, Staples, Walmart, TigerDirect etc
on line, down the left side all the choices for what you are looking for as size,make,internals, Operatingsystem, et al
Install Linux along side or in place of windows. Mint is very user friendly.
