Except that's not the case according to the Flight Simulator 2024 FAQ
For any content you purchased outside of the simulator, the Community Folder will continue to work as it did in MSFS 2020. Any content in your MSFS 2020 Community Folder can simply be copied over to the new MSFS 2024 Community Folder, and the vast majority of that content should work in MSFS 2024. For any content you purchased in the Marketplace in MSFS 2020, that content will show up as owned in the Content Manager (in MSFS 2024 called “My Library”) at launch for you to use in MSFS 2024, and the vast majority of that content should work in MSFS 2024. This availability does not require developers to sign off on their content.
I've become a big fan of mini PC's for home server use these days (with NAS systems for storage duties). Low power, low heat, low noise, and very affordable.
Beelink on Amazon makes a good selection of them. Always watch for sales. I have several of their machines and have been pleasantly surprised by all of them. The latest addition was one of their N95 systems with 8GB of memory. It hosts Jellyfin, Deluge, Wireguard (client and server), dns, forgejo, etc.
