I am not a technical individual, but I do know a few things about pc's.  The issue I have is with the refurbishment of the product that was delivered to me.  The four usb ports on the front of the unit are inoperative.  two only supply power to devices and the other two are completely inoperative.  Not cool!  The Wi-Fi on the unit is extremely poor.  I have a more than adequate signal to my new used pc, but it seems to be having some serious connection issues even though it is showing a strong signal.  The mouse and keyboard that was supplied is of cheap quality.  It appears to me that someone just slapped this unit together with no regards to the new owner!  Not impressed with this purchase or the unit what so ever!
