Good computer with Windows XP already installed. Also includes Service Pack 3.The down side is as follows:1) No floppy drive.  Although you don't usually fine a floppy drive on today's computers, I feel that with an old computer running an old operating system a floppy drive becomes moue necessary.2) No standard keyboard and mouse plug-in.  You have to use a USB keyboard and mouse.If you are trying to replace an old computer, a floppy drive and keyboard and mouse ports should be there.
