This is the second purchase of this PC. The first one was perfect in every way. It even included a DVD player which was not in the spec and a pleasant surprise.This second purchase had issues. The on board NIC RJ45 connector was intermittent. I tried several cables and still had problems. It would work for a couple of days and then act up. I placed a USB NIC adapter and disabled the on board NIC and has worked fine since. After a couple of weeks, the SSD drive started causing the Windows blue screen with QR code. I ghosted to a larger SSD and now seems to be ok but was a pita getting to that point.
