I got this for about six hundred dollars less than retail and was excited to receive my purchase. Despite some seriously annoying delivery issues, the first machine arrived. Yes, I said the "first." I had it for less than 24hrs when after a windows update it would not come on and the lighted emblem flashed at me. Amazon, however, was happy to replace it. After I received the second one, I ejected the dvd through file explorer, and the spring loaded door literally was knocked out onto the floor! Thankfully, HP provided in-home repair and the door was fixed.It is a beautiful machine. Quiet, powerful, and meets all my gaming needs. It has room for an additional SSD, two HDD hot swaps, and plenty of ports.Now, about the BSODs with the QR codes....
