Computer
Used computers in various configurations.
Most of these are older computers that have been repurposed from their original office or home use running various versions of Windows. Most of them have been reformatted and had an appropriate version of Linux installed on them. This is not because I don’t like Windows; I make my living supporting Windows. Linux has a much smaller footprint and will run faster and give more features on these older computers than a modern version of Windows. In many cases a modern version of Windows would not run at all on these computers.
