Thanks! I'd like to have built a full size cabinet, but we are a bit cramped in our house so my wife would have not been on board with that. This worked out really well from a space point of view and I really like having a cocktail configuration.

Perhaps the speaker position is not ideal, but considering the audio from these old games is mono and not high fidelity, I really don't think the difference would be great. I did test the difference between having the speakers projecting into open air up and into the wood and it was night and day. The sound resonates the wood and the sound is much better. The case is elevated slightly on rubber feet so the whole case resonates the sound pretty well. I also don't think the speaker would have fit on the side, interfering with the monitor.
