This cabinet looked so good that I decided to copy it exactly (I hope you don't mind). I just orderd all of the parts in your instructions except the computer, TV, and speakers. You should get a commission! Some of the parts cost a little more than you listed including shipping. So far, everything cost around $1400 shipped. I felt like this is a good deal compared to buying a slikstik cabinet/controller combo for $1700 + $90 for the overlay + $300 shipping = $2100.
Originally, I was going to go with the overlay and marquee with characters on it, but after looking at other MAME box pictures on the internet, I decided that looked too gaudy and tacky. No offense, but the mame marquee with lighting bolts seemed pretty dorky to me. However, I could not deny how awesome your box looked, so I decided I better not risk anything and just copy exactly what you did.
The one thing I realized maybe is missing from your setup is plexiglass over the TV. To me, that seems like an important feature. Is there a good way to include it with this setup?
Thanks!
