$10 Facebook Marketplace Computer

The title says it all , Last night I picked up a desktop PC for $10 of Facebook it has a AMD Athlon 5150 CPU and 4 GB of DDR3 ram came with a fresh windows 10 1903 install , Currently I Have an IBM model M keyboard from 1994 hooked up to it and a Microsoft mouse with scroll wheel from about 1997 Hooked up via the 2 PS/2 Ports on the back of it it has been along time since I had a PC with 2 separate PS/2 ports instead of that stupid combo jack thing that some laptops and desktops had for a little while , Anyways does anyone know what I should do with this thing I may put Linux mint on it later today I originally got this thing just for the LG DVD drive it had in it since I thought that in parts alone that would be worth more then the low asking price and it turns out I have an entire working computer with it ! Im thinking of selling my 2012 iMac 27 inch that has 16 GB of ram because non of what I want to run works on it even with Wine installed currently it has mac osx 10.8.5...
