My sister had a XP desktop pc that was very obsolete.
I recently bought her a HP z240 SFF desktop with Windows 10 Pro for just $17.24! I had a credit card discount at Amazon.
I also bought the same pc for $135
HP z240 SFF. The one I received had a 1TB ssd drive and i5 7500 cpu. It can hold 3 hard drives. It was built in 2018 and also could run Windows 11 as it has the TPM chip. Microsoft says the cpu is not supported, yet I have Windows 11 running in Oracles free VirtualBox.
