I've got a cabinet (gutted), buttons, and IPAC. What do I need to buy? Probably .187 female disconnects, but what else (I can't think of anything, too little sleep recently). I appreciate any help, thanks.
What method does the PC hook to the monitor and what type of monitor is it? What condition is the cabinet in? Do you plan on modifying it in even a minor way? Do the non-PC components already have power? How will you be getting sound? Does the marquee area light up properly?
There are LOTS of questions that could use answering before any good suggestions can be made. However, if you're talking from a strictly electrical stand-point you will want:
wire (18 or 22 gauge)
quick disconnects
wire strippers
crimpers
zip ties
tie-downs
possibly a terminal block
surge protector (after all, you'll have a PC in there)
Non-electrical considerations:
maybe speakers
maybe a marquee bulb
maybe a VGA breakout cable
maybe paint, plexi, wood filler, t-molding, speaker grill, screws, wood, etc depending on the condition of this cabinet and your plans for it
