sliding rear panel for console-cabinet

Hi All -

I’m making a slightly bigger version of this project here https://www.lumberjocks.com/projects/413234

One of the requests I got for it, is behind the right side of the console – is to create a panel that slides up and locks in place, preferably at a slight angle so when they play their records, they can display the sleeve behind the record player. I have a few thoughts about how to create this, but most of my solutions include basically routing a closed ended dado with an “L” at the end and using dowels to slide and lock into place.

It’s a complex solution, so i was wondering if someone had a simpler answer, like some kind of locking drawer slide or something. (I already looked for these, and they definitely exist, but I feel like it’s fairly inelegant and bulky as a solution.

Thanks!
