What set of spare parts for the Raspberry Pi 3 B+ can be purchased to turn the "raspberry" into a standalone mini-PC?

Question

Computers

Greetings, dear comrades. I ask you to tell me which kit option would you recommend for turning the Raspberry Pi 3 B + into a mini PC (tablet type)? Yes, you can take a tablet, but the soul wants to "pervert" and make it out of "raspberry". I saw some options when people take a 7-inch screen, put a Raspberry Pi on the back of it, but I also want to somehow organize some kind of powerbank in parallel and suitable for the power needs of this device. Maybe someone has a link to a kit for buying a set "screen (from 7 inches) + case for splicing with Raspberry Pi + battery for autonomous power supply (at least for a couple of hours)". I know that raspberries are not so rare now, maybe someone came across a suitable set, or maybe just separate spare parts, so that later they can put everything together?
