This small bar top arcade uses a 17″ monitor with a 4:3 aspect ratio (the old non-widescreen ones) and is made from less than one sheet of 1/2″ plywood. I also purchased 20ft of 1/2″ t-molding, but that is an optional step.
Overall dimensions are are roughly 19″ wide, 17″ deep, and 28″ tall.
See the full build video and tutorial for this project here — How to make a bar top arcade cabinet.
The internals/electronics for the machine are described in detail in my full size arcade cabinet series.
