I got this HP PC from Sunset Micro and I was able to contact them and they installed the OS that I wanted at no additional charge. One of the categories is about gaming and I give this PC four stars only because it comes with 8GB of RAM. I have increased the RAM in this PC with 32GB. I do graphic art work so I need a lot of RAM.If you need a REAL computer this is the one I recommend. The value that you get is exceptional.
