It's been a month now. I topped it with Crucial 16GB Single DDR4 2133 memory & Samsung 960 EVO Series - 250GB SSD, and it delivers an amazing performance & speed, you can literally see the difference if you had upgraded from an old PC. Remember, if you are ordering it with optane pre-installed you cannot also use M.2 SSD since it share the same slot. You have to use 2.5" storage in that case. If you have experience with computers the setup is not hard. The reasons I couldn't give 5 stars is due to the noise from fan, on a quite environment it may bother you. I don't know why intel can't do a fanless case for how much it costs....
