Step 4: Conceal Everything Inside the Cabinet
This step will vary depending on the size of your cabinet, size of your PC and monitor etc...
Basically, you shove all the components into the box.
I had to take my PC out of it's case and mount the components into the cabinet. There is a surge protector inside that the PC, monitor, speakers, and marquee light all plug into. I connected this surge protector to the male power plug that sits flush with the outside of the cabinet. I also put a rocker switch that turns the surge protector on and off. This way, one switch controls everything.
Add USB ports at this point. You can use a USB extension cable, just plug one end into the PC and leave the other end exposed for access outside the cabinet. The PC I used had an external USB control board, so I used that instead.
I made a Nes controller port that works with the PCs parallel port. There are plenty of instructions available for this online. It would require another instructable unto itself, so please look it up. Once the ports are wired up to the PC, leave the ends exposed at the back of the cabinet.
For speakers, I just took apart a set of desktop speakers. I installed them next to the marquee light, facing downward toward the screen. Be sure to drill several small holes in the wood that the speakers will be facing.
Connect a small fluorescent light kit and mount behind the marquee.
For the marquee design, I just printed out the logo I wanted and sandwiched it between two thin pieces of plexiglass.
Get the monitor in the exact spot you need and bolt it down.
Once all of this is done, test it out and if you are happy with the results, install the control panel and the plexiglass over the monitor.
For the bezel around the monitor, I used a sheet of plexiglass and spray painted the edges to hide everything except the viewable LCD area.
