After lurking on these forums for a couple of years now and driving my wife nuts with talk about arcade cabinets and jukeboxes, I finally started to piece together my own ideas.
For a first project, I figured might as well start off small. Well that, and I don't really have room for a full cabinet at the moment. So a floor standing, upright jukebox it is.
15" ELO LCD touchscreen to be mounted at the top. Speakers, amp, and the AT PSU go in the bottom section. A full size ATX motherboard, PSU, drives, and accessories go in the middle section.

Nothing drastic about the basic shape. But a decent amount of time went into keeping it to a small footprint, but being able to fit all the needed components.
I have a set of surface mount speakers and an amp from an old car audio setup that were just collecting dust in the basement. Might as well put them to use. A quick test of powering the amp off an old AT PSU, also collecting dust in the basement, and presto, we have a working sound system. A hooked up one of my iRiver H320 MP3 players for a quick test. The speakers actually have a decent sound, with some bass. It won't shake the house, but it can get loud if needed.

Here is just some of the pieces I have ready to go. Speakers, amp, AT PSU, dual 12" blue cold-cathode kit, dual 12" white cold-cathode kit, a sound activated power module, a couple of rocker switches, and a momentary push button vandal switch. Oh, and a spool of chrome t-molding.

The rocker switches will be to turn the lights on/off, the push button is for the PC power switch. I will be taking apart another PSU for the power plug and switch to turn the amp PSU on/off.
Plexiglass just came in today. One sheet has some shipping damage in the corner, but nothing major. A sheet of "modder's mesh" has also been added to the pile.
A couple of weekends ago, I picked up some 3/4" MDF and started making sawdust on the back patio. Not bad for a couple of hours work. The real pain was cutting the 45 degree angles with a hand held circular saw. It only took about 7-8 attempts, between two different saws to figure out a method that worked. I forgot to take pictures during the cutting, so here is the result at the end of the day.
