Suggestions for Lenovo Desktop to Buy

Customer has asked me to get a new computer for them. Their current system is a Lenovo desktop running Win7 64bit Home Premium. I would like to upgrade this system to Win 10 and then take out the hard drive and put it into a newer
Lenovo desktop running Win10 Home Premium. This will avoid having to reinstall all the programs.

I’m looking for a good refurbished system that this should work on, as up level as possible hardware-wise and with reasonable expectation it will last a long time. I always prefer business computers for this reason but many of them are Windows Pro.  Do you have any suggestions for a Lenovo desktop this might work on? Output from Belarc advisor and Speccy is below.
