As a number of reviews attest, this desktop appears to be a good value, but some of the components appear to be of such poor quality that I wished I had not purchased this.  I have had to return mine (by mail, since there aren't authorized walk-in service centers) because of a USB unit that failed.  Potential buyers may want to know, also, that the CD burner is really below an acceptable quality, in this consumer's opinion.  This primarily is an issue when it comes to ripping digital copies of CDs.  It is extremely slow to do so, it typically takes a half hour to rip a single CD, for example.  The drive also spit out one disk midway through a burn, for unknown reasons.  And the drive does not support high quality digital rips (copies); it uses caching, which interferes with the accuracy of the copy that is made.  At it's worst, it made a couple of terrible sounding copies of CDs.  I will need to have the CD burner replaced at my own expense, Acer did not honor this concern (although the tech support was otherwise responsive/knowledgeable and the wait time was brief).
