Lenovo's IdeaCentre B540 is an all in one PC, built into a 23" 1080p touchscreen that should make using Win8 a little more user friendly.  The specs are not up to gaming, the Core i3-3220 @ 3.3GHz only has Intel HD2500 graphics but with 6GB of RAM and a 1TB HDD it should serve well as a light workstation or home PC.  TechReviewSource does mention a higher end model containing a Core i5 CPU and a discrete Nvidia GPU but with the heat constraints of this type of form factor you are still going to have troubles playing the newest FPSes.  Check out their preview here.

"The stylish design of the Lenovo IdeaCentre B540 is one that catches our eye in tandem with its budget price tag. The 23-inch 1080p touch screen works well with Windows 8 and looks great for multimedia viewing. Performance is good, especially for the price, but it does make a slight compromise with a Core i3 CPU."
