I was excited to use this and it worked well for a few hours. Suddenly while using Firefox to Google something the screen started to jitter and I got a "cannot allocate memory" failure. Shortly after the screen went black. I rebooted the pc and it no longer had an operating system. After having my IT guy look at it he stated the hard drive was no longer recognized by the system and it was nonfunctional.  The drive burnt out and the most assistance I got was "reorder it and return the old one through Amazon." I'm not impressed with the customer service and begrudgingly ordered a new one as this is the best priced pc in my needs and form factor. Here's hoping this was a fluke but time will tell. Wasted time, energy and gas to return this. Buy at your own risk!
