Long time reader, firs time poster.
First I would like to state how awesome this site nad the members of the site are.  I have learned so much in the time have been reading this site.
                                     My Project
I will be building a MAME cabinet with a twist.  To preface, I have already built a Barmonkey (
www.barmonkey.net).  A group of college kids decided to build a box that could make mixed drinks.  I went a step further and made a portable Barmonkey that runs off of CO2 and a laptop.  You select the drink i.e. long island tea, and my barmonkey will make it in around 10 seconds.  
My first version will be called the 'BeavArcade' - last name is Beaver.  My second version will be the 'BeerCade'.  My MAME machine will be in my basement/gameroom/bar It will be a fully functional MAME machine with cup holders on the side.  These cupholders will have taps/spouts above them.  An arcade button can be used to poor a beer or you will be able to launch a frontend that has the choice of your beverage.  An all-in-one true cocktail cabinet.  
I know a lot of people on here are true "keep the arcade stock", but I feel this will be a neat project.  
Please let me know what you think.
If you have any questions about my project or the Barmonkey I built, please let me know.  I have pictures on my website I just need re-organize a bit.
