If this is going to be in a place where it will be a primary television, then you oughtta just rethink whether you really want an arcade cabinet or not.
If you really want to build a typical standup arcade cabinet, then you are going to have to make sacrifices with the television's viewing for other purposes.
The one in the pic, where the controls are under the monitor area, seems like it would have you standing too close to the actual monitor for what I would consider comfortable.
My cabinet is an Ultimate Arcade II design, and the monitor can be viewed just fine sitting from a distance, but it is angled, and it is NOT what I would consider ideal. It does make a great secondary television though, and I do use it for just that actually. My cabinet faces the kitchen, so we often have the tv on while cooking.
