Couple more thoughts:
-- With any of these cabinet projects, make decisions that would help you re-sell it later. Many of times have I seen people half-ass the installation of their hardware, cut corners with the build, or just hacked up harnesses or panels just to make it work for their current situation. But down the line, you may (most likely) want to sell your project, and the more work you can do initially to make it sales-ready the less time and hassle you'll have to deal with later.
-- When Mame'ing up a renovation project, throw nothing out. Chances are high that there is someone looking for those pieces to restore their projects, and you can make a little bit of coin (or karma) back by selling/giving those parts away.
-- Arcade cabinets are not meant to ferment alcohol in. Just sayin'.
