How can I update the outdated wood exterior of my new house cabinet to better showcase my elephant collection?

We recently purchased a house that has a built-in cabinet. I’m planning to showcase my elephant collection in it. After peeling off the wallpaper inside, I found that it’s green. I want to paint the inside cream or white. But I’m not a fan of the wood color on the outside, it looks so old-fashioned. Any ideas on what I can do to update it?
