I bought this new 6 months ago for $950, I installed 32GB of DDR4 3200Mhz RAM and used it as a mobile gaming machine. It did a phenomenal job, and played AAA titles at amazing framerates and quality. The screen is 1080p 144hz, and it does have HDMI and Thunderbolt II ports available if you would like to connect an external monitor. 3 USB 3.2 ports allow for the best data transfer available today. It has one 512gb M.2 installed, there is a slot for another available if you pop the case open. I had installed a Samsung Evo 2TB M.2 drive, but I took it out for the desktop machine I built. If you have any questions, feel free to contact me by text. I do not answer calls from numbers I do not recognize.
