People who have rebuilt Vintage Honda CB’s (Late 70’s/early 80’s), where do you remount the battery and other electrical components?

I have a 1978 Honda CB400A that I want to turn into a Cafe Racer, and I don’t want the side panels in my build. I’ve seen pictures of CB’s without them, but I have a few questions:How do you get the Airbox out?Where do you mount the batter that usually sits behind the side panel? And finally,Where do you put all of your electrical components?
