Was looking for a low powered, mini PC to add to my growing fleet of nodes and came across this little guy. You get a decent amount of performance for a 10W Intel Celeron 4c/4t chip with dual channel (I recall reading this somewhere but I could be wrong) 6GB LPDDR4 RAM, 128GB eMMC drive (can be expanded with M.2 2242 slot which I'd do immediately since eMMC is just not good enough), WiFi+BT, oh and Windows 10 64-bit Home preinstalled. To get such small footprint (smaller than a RPi I think?) the device PCB is broken into layers, if I'm not wrong the tech is called Intel Foveros 3D.
Some reviews: techradar, liliputing, someone managed to play a bunch of simulator games on it quite smoothly YouTube
I personally bought the 2-pack (~$420) and overall I think you get a lot for the price, especially if you'd prefer a Window box. Make sure to pay with free foreign tx fee card as you'll be charged in HKD.
EDIT: thanks to kogi, here's the link for secret perk (extra USD$6 off).

This box is certainly interesting to put that many things in a small case. One thing to concern is the after-sale support (drivers, doa etc.), and a one-year warranty is too short to me.
This can even be the next Mac Mini you know ;)
