Sorry for the lack of updates on this build... The cabinet has been out in my garage where it's been over 110f degrees for the past 45+ days. The past week or so I moved the cabinet inside into our living room. Since moving it into the living room I've gotten more work done in the past week than I have in almost 2 months.
So far; I am REALLY happy with the outcome on this build so far. Since I built this cabinet to match my 42" playfield neither a regular nor widebody lockdown bar would fit the cabinet. I had to have a custom lockdown bar made to match my 24 1/2" width cabinet. I ordered the custom lockdown bar from Virtuapin.net and had the undersides for a Williams/Bally lever guide assembly. A friend of mine was able to acquire a lever guide assembly for me for free. After a little dremel work the lockdown bar was nice and snuggly installed. The lockdown bar and guide matched perfect. There is NO movement with the lockdown bar at all. For glass I was going to go with a tinted glass, but decided at the last minute (while at the glass shop) to go with 3/16 clear tempered for both the backglass and playfield glass. Unlike my previous pincab build, I got the measurements perfect. I probably could have went about 1/16 smaller width so it could slide into the rails easier, but it works. After the glass was installed my DMD reflection was off by about 4 or 5 inches due to the angle of my test piece of glass. Thankfully, I was able to take my monitor board that has my speakers and DMD LCD attached and slid it carefully along my table saw to cut off 2". The 2" was just enough to make the DMD reflection appear where it should. All of the pics so far are without any kind of tint or reflective surface for the DMD. The DMD looks a little faded in the pictures below, but in person it looks pretty damn good and clear.

The smear on the side of the cabinet is from my unsteady hand with the camera.

2 saucer flashers are mounted near the rear of the playfield. Actually they don't even hang over the playfield at all. The playfield is mounted so there is no LCD bezel showing at the front of the cab. The playfield starts at the lockdown bar edge and goes back to about 3" away from the backwall. You can't see the 3" gap between the back end of the playfield and the back wall which is nice because it helps with airflow and heat removal.

Once I got the flashers working with Visual Pinball/PinMAME I decided that 2 LED's just were not enough. I ended up installing 3 more LEDs. So now I have 5 LEDs total on the playfield. Center/Left rear/Left front/Right rear/Right front. Right now I just have the non-saucer LEDs in temporary position with doublestick tape until I can figure out exactly where or how I want to mount them. Visual Pinball & Pinmame are set to interface with the LEDWiz and tells the LED's when to trigger. The LED's are in sync with the flashing within the game. The coin button flashes when the table is out of credits, the start ball flashes to tell the player to start the game, then the launch ball button flashes when the ball is in the shooting lane. The Exit button also flashes to let the player know to press it when they are ready to exit the table.

For the most part this cabinet is finished. I'm going to be upgrading the CPU and video cards in the very near future. Once I added the LEDs this eats a bit of CPU cycles and mine just isn't up for it. While almost all tables are playable there is a noticeable stutter when all the flashers start going off on tables.
I still have a couple minor things left on my "TO DO" list.
1. Artwork - created, printed and added to the cabinet.
2. Mount/secure the DMD monitor/Speaker board.
3. Get speaker felt to cover the speakers. Hopefully once the speakers are covered they will not reflect in the glass.
4. Cut and install the rear access door for the head.
5. Hide sides of playfield and backglass LCD's.
6. Create and install button labels for front HyperPin buttons.
