Do not purchase this product!!1) When it arrived, before even taking it out if the box I could hear something clanking around within the tower. Upon inspection, it was one of the fans that had come unglued from the back of the tower and was hitting the motherboard. Again, this was before I even finished getting it out of the box.2) The wireless dongle doesn't work after installing the drivers on the (obviously used) mini CD that it came with. Only way to get internet was through an Ethernet connection.3). Restarted the tower on the 2nd day and received a "An operating system wasn't found." error. Troubleshot in the BIOS and diagnostics showed nothing is damaged.4) Have made multiple attempts to call BAP Technology to receive a refund to no avail. Just about everything that could go wrong with this product did so, within the first 48 hours. Save yourself the trouble and get something that isn't refurbished.
