@kiddk1: I like your spinner placement, I think that's what I'm going to go for. I made a few cardboard mockups, but not of my final design, actually. I know that's not the best approach, but I'm just going to go for it. I can always get more wood if this doesn't work out (and I'm out of cardboard anyway).
@SavannahLion: In a way, my CP will be somewhat similar. But, since I'm not using a mounting kit for the TB, I can fit the whole fighter setup straight across. I will be putting either a full lockdown bar (for the pinball feel) or just the corners on mine, though.
I should clarify, though -- this isn't for a cab, it's a desktop cp. That's why I was so set on making it 23" (after trying out several other layouts). I mean, yeah, it will look a bit crowded in, but I'm kind of taking a utilitarian approach here. I want to make this as functional as possible so me and my friends can play as many arcade/pinball games as possible. It'll be way easy to transport, too.
Thanks a lot for the feedback guys. Any other advice is also welcome.
