Not the OP. In my case the client want many all-in-ones.I proposed a small CPU to fit into the notches on the back of a Specific monitor. I used an Intel Compute stick which only needs power, an HDMI cable and a powered USB hub. This gave me an All in One Computer functionally for less than half the price. It also had the benefit of being up-gradable by swapping out the Compute stick for a newer model. When the client saw it he thought it was an all in one and thankfully appreciated the cleverness. (Financially, I got the contract)
