It may be ambitious, but I am planning on building another Wine barrel cocktail cabinet, but this time using MAME with the option of having a juke box. The plan is to build a subwoofer in the base of the barrel and design swappable panels a la Doc's Modular panels.
I am planning on using a 19" monitor this time. The plan is a 4:3 monitor so it fits, but am wondering if I should be looking at a widescreen due to the 2 player split screen.
