My expensive drafting and design program is quite old and only works of Windows Pro XP  Service Pack 2.  To repair my five year old computer would have been a minimum of $150 plus any needed parts.  I paid $156 for this computer, with a screen, mouse, and Windows XP  installed.  It was literally, plug and play.  Not a single problem and the machine looks like new.  I plan on buying another one for a backup.  I would buy from the same company too.
