Long shot, but did Cave ever have any sort of dedicated Cab?

I'm know it's a crazy question considering the way Japanese arcades are, but I just thought I'd ask anyway. I've heard of crazier dedicated cabs in my day. I'd kill to own something like a dedicated Dangun Feveron machine, or something among those lines.

Never heard of a dedicated CAVE cab.
I usually see some type of Taito Egret with shmups on them...

I havent seen a dedicated cab for any Japanese game in recent years.
