This is a very good system if you are a user of older programs.  The equipment arrives promptly as advertised with clean hardware, XP/3 software, cables, keyboard, mouse and monitor. All your older XP program disks will install and run as designed. This dated software system is no longer supported by its creator or those who once supported the platform. Internet downloads of legacy programs such as browsers and drivers for HP printers are either not available, will not install, or are not supported. This is not an internet platform.  XP IS WHAT IT IS.Hard Drive Enclosure for 3.5 2.5 Inch SATA SSD HDD USB 3.0 to SATA III Hard Drive Case for older HD. New ones arent supported read the HD box. 32 GB thumb USB works well.Update:Turns on fast and has a clear 17" screen. Although the mouse works I could not type by using the keyboard, I tried all the USB slots and no go. Not a concern for me but your mileage may vary. I have a drawer full of spares and so not worth the hassle just thought it should be said.
