Nope. On closer inspection, it's a tablet resting on a stand; it's not mounted with a VESA clamp or arm like most monitors would be. You can see the USB charging cable is plugged into the side of the tablet as well. When you compare it to the keyboard and headphones next to it, it must be about 11-13 inches in size, so it's unlikely to hold a mini PC on the back as it wouldn't be heavy enough to prevent toppling over. The stand would be bigger too if it could hold a mini PC.
