It really comes down to what the consumer is comfortable with putting together. I think the Arcade 1-Up cabs look pretty sweet. I really want to get my hands on one of them to see what the material and build quality is like. Because if I do get a hold of one of those, I'll probably mod it to connect a Raspberry Pi so that I can do exactly what your designs do. I already have a Pi. I just don't have the tools or time to fabricate the rest. Also, there's a bit of advantage of not having to deal with a full arcade footprint. I'm already halfway through matting up my garage, so I don't exactly have a whole lot of free real estate in my house.
I think we're talking about the same things really. We're just splitting the difference on how to get there.
