Now it's finally finished. Here some pics:
Front view with customized hyperspin running (I love robotron 2084, it's the reason I built the bartop
)
Left and right side view with the cut out MAME logo glowing.
Back view. I decided to use a metal plate with holes to cover the backside. So there cooling issues, also you can't see into the MAME (at least you won't as soon as I cover the back reflection of the marquee light :p ). The plate is held in place by some power magnets hidden in the frame.
Control panel in the back: There is the main power swith, red button to start the pc and white button to turn on the monitor and sound system. Next to it you find the volume control and a headphone jack. Inside view. On the left side you see the subwoofer, on the right side is the pc.
The last image shows the wireless keyboard with integrated mouse pad, it's held in place by velcro fastener.
You also notice there are some LED stips. These are powered by a 12V battery. It turns on automatically as soon you remove the back metal plate. Therefore it's easy to maintenance the bartop with the powercord unplugged.
