Here is my wife setting up Windows on her computer. She also transferred her apps, settings and data from her dead computer’s HDD to her new computer just as I did. For her new computer she selected an HP Z2 G5 Small Form Factor Workstation for the same reason I selected my computer. We both had very little room for the computer.
Her new computer is small enough that it sits on top of her table/desk. with the Wi-Fi adapter and USB adapter on top of the case.
