Yes, I bought from Amazon this PC is TOP. I bought at the same time a 4GB RAM array. Of course, I added. For that I had to open the door for this purpose. On this one, stood a "logo". In doing so it broke and I 'learn also that thus, I lost MSI warranty. I would be grateful if you take into account the remarks and defend my cause from the manufacturer, if a trouble arose. I expect an answer; thank you.
