I think an interesting LTT video (or possibly a Scrapyard Wars series) would be to build a modern PC driven Jukebox.
Two key feature of the Jukebox...
The key part would be elaborate (over-the-top) RGB affects that sync with the music.
The Jukebox would need speakers that can handle both a large party setting, or a smaller setting where the music is just background.
Other considerations...
The PC itself would NOT need to be very powerful.
The PC could have local stash of .mp3 files, plus connect to several streaming music services.
