I purchased a refurbished HP desktop thru Amazon... this, of course, eliminates the HP waranties...I purchased Asurion insurance thru Amazon... which will be required... the general functions of the computer are efficient, however, the audio system is extremely pathetic...some times the single speaker in front might work... the plugs in front and rear do not work... and the system software CANNOT address or troubleshoot these problems, or provide assistance... Amazon, of course, has designed their website where you cannot contact them in such cases... you can tell them you are happy... or not, as in this case... but, they provide no further assistance... standard corporate b.s.
