Nov 2023.  HP Prodesk 600 G2 Micro Computer Mini Tower PCThe computer had Windows installed, as shipped, but it was not used (don't need the computer connecting to the Microsoft mothership to send who-knows-what information to the MS eye in the sky).  Ran the onboard computer memory and hard disk checks - all passed.  Linux Mint was installed after computer setup; however, version 20 was used due to issues experienced at install with the EFI secure boot features of the computer.  After v20 was installed, Linux Mint booted and then the upgrade to version 21 was started.  All smooth like a hot knife in butter.Graphics testing was completed using online utility sites and testing videos posted by vid experts (e.g. via yootube).  The computer runs very quiet with just a slight fan hum.  No issues with speeds (video streaming or network traffic).Though this hardware is several years old (from refurb/off-lease); hopefully, it will function for a long duration.
