I won't be able to take pre-built components apart just yet. Most review units have embargo terms that prevent reviewers from taking pictures like that.
Believe it or not it's a really stable machine even when it's on the riser. There is a little movement but both my co-host and I played it pretty hard at a point and didn't have any issues. They've also included some mounting brackets to keep the system attached to the wall to prevent it from falling over. Similar to what you would see with IKEA furniture. The riser had some holes in it to screw it to the base of the arcade system, I assume that was to lock it in permanently if you so desired.
Can't open the box up right now but it does look like you can replace them. You can also unscrew the ball heads and replace them with battops if you wanted.
This wasn't an issue with mine as you can see. The printing seemed high quality and didn't feel like it was going to peel anytime soon. The controller area doesn't have a plastic cover or anything, so that
might be an issue a long long time down the road. However since this isn't really meant to be used in a public arcade I believe it will hold up. The screen has a plastic overlay with an artwork bezel that was really well made. They even kept the 'Barlog' misspelling from the original.
Here is a closer pic of the connecting cable and port plus the backside of the controller box:
As I mentioned I can't do that quite yet. However here is a closer picture of the box. It's about the size of 2 decks of cards or so. The power brick connects through a wire extension that goes straight to the box.
