HP cpu with very low quality  add-ons.  The mouse and cd drive were mal-functioning from the start.  HP service desk was bad.  I spent a few hours trying to get it running.  Then called and waited HP service, on line... said. " maybe we can repair in in 30 days".  The whole situation was a pathetic "sellers market".  We have several HP printers and CPU in our office.  I just can't undertsand why this was such a low quality item, with low quality customer service.
