Hi, I have a Dell Optiplex 790 (SFF) with an Intel i5 2500 which I no longer use, but which a local church would like me to donate to a local kid who needs a PC for home learning during the Covid-19 lockdown. I have upgraded it to the latest Windows 10 H121 O/S version, no problems, nice clean install getting rid of all the old stuff. All seems to work nicely, well built piece of kit.
