Not done - never done, of course.  
I had it outside on my porch for Halloween.  One kid said that our house was the coolest house he'd ever been to in his ten years of trick-or-treating.
Today we re-arranged the house.  I said "hey, let's bring the cabinet into the house" and suprisingly the wife agreed.
Luckily, I have a hand truck.  A really good one.  Unfortunately it's solid steel, not aluminum, so it adds a ton of weight to whatever you're moving.  When you're on a flat surface, it's not that big a deal.  But when you're trying to move it upstairs with your not-so-strong wife...
Luckily it made the journey intact.  Almost didn't, I thought she was going to lose it.
Keyboard hack got bounced around a bit, one wire came off.  Quick touchup with the soldering iron put that to rights.
Still need to do a little tweaking in software.  Lock down ArcadeOS and get a few more games in there that will run on the hardware I have in the cabinet and with the controls that I have.
One idea I have is getting some translucent leaf buttons for the P1 and P2 and getting the LiteMite.  They'll blink in Galaga/Galaxian, and that would be cool.  Would also be relatively inexpensive.
