Well, after reading many posts on here I decided to start my own build.  I was hesitant to post a thread as I certainly do not have the skills of many people on here.  In the end though this seems to be a very welcoming community so I decided it best to do so and hopefully get the insight from others to make my build even better.
I am attempting to make the OND Metropolis cab.  Thanks to  

 OND for putting this out there and to all who have posted on that thread.  It has been a HUGE help.  It is a great design and the instructions are fantastic.  One change I am planning is I modified the CP slightly to make it a bit larger.  I plan to have both a track ball and spinner, so I went 14”x30” with a slightly rounded front.  Here are the other details and my current progress.
I have most all of the wood work cut out and partially assembled.  To keep the costs down somewhat I am using a Dell XPS Laptop and 19" 4:3 monitor that I had lying around.  The rest of the parts I bought from Ultimarc as it was easiest to get from one place.   Andy was great and helped out a lot. 
I-PAC ultimate
20 RGB LED Ultralux buttons
2 - J-Stick Joysticks with RBG illuminated Handles
Spin Track spinner
U-Trak  Tackball with LED
Coin door / Mechanism
I plan to use a theme similar to Chapels with the blue lightning as that is what my wife liked best.  And of course I needed her happy and on board to actually be able build this thing.  

  I will probably use Gameongrafix per the recommendations of others to get the marquee, CP and bezel art.  Still unsure what I want on the sides so I will wait a bit.
Ok, now for my questions.
1. - In using the laptop, I was unable to attach to the disk drive power that many mention in here, and in some of the supplied instructions.  I bought a 5v wall wart to plug into the I-Pac and power the LED's for the buttons, trackball and joysticks.  I am however stumped on how to power the coin mechanism (12v), LED for Marquee, and the LED's for the front to give a little glow down each side of the coin mechanism.  Is there some other thing I can buy to easily be able to plug these into an external power supply of some sort?  Splicing wires and such are not a strong suit for me.  It is one of the reasons for the choices I made with Ultimarc.  I just need to plug most of it in.  

2. – I hope to be painting shortly and have noted the comments on using bondo for filling the holes.   What type of paint and primer should I use?  Is Latex OK or should I used Oil based?  I plan to use a foam roller as I believe I read that was best on one of the other posts somewhere.  I worry about my ability to make it look good with canned spray paint.  
3. - I have the pc with Maximus Arcade mostly set up.  I still have to program the buttons and led's once I have the CP put together.  The only issue I have so far though revolves around Steam.  I purchased Pinball Arcade to play on the cabinet.  I have it set to offline mode as I do not want it updating now that I have everything working.  The only issue I have is that it has a popup asking it I want to stay offline, and I need to use the mouse to select this option.  Is there any way around this?  I have tried searching and come up empty so far.   It is very annoying  

  and I am not sure how this will work once the pc is in the cab.
That's it for now.  I have tried to attach a couple photos of my progress.  Hopefully I did it correctly.  I will also update now as I move along.  
Thanks for any help you can give.
