Amassing a media library is simple enough, and software like jellyfin can pull in media info and make your media streamable on various devices with a polished UI.
However, finding good quality (in terms of merit) movies and shows is difficult.
Maybe start with movies critics or a movie discussion platform like letterboxd to see what others are watching/rating movies.
What country/region are you in?
In the North America, I'd recommend Novelkeys, Omnitype, Mekibo, Cannonkeys and spacecables (spaceholdings) for GMK sets
A better approach is to keep your eyes out on Geekhack. The majority of keyboards and keycaps go through an interest check there, and then the designer announces all regional vendors/prices prior to a groupbuy.
