Yeah, my nieces are all into Fortnite. They begged me to download it on my Switch for them to play. I tried it out a few times, it's not really for me. I still prefer PUBG, or the now defunct Radical Heights (<--- it was fun for the 80's-stylings). Funny thing about Fortnite on the Switch, it makes the GPU work overtime. Much more than BOTW! An hour of play will make your Switch run pretty hot.
Cool shelf cab. Good for the kids I would say, having a dedicated gaming "station" that you can swap consoles in and out of is robust for having console options.
How are you handling the audio? Speakers? Headphone jack?
