Many cities and towns across the Rockies in North America have elevations above 1800 meters. That's the starting point. By comparison, "high" cities in Europe, like Bern (500m) and Innsbruck (574m) don't Even come close. It's not a factor of one thing like having a manual transmission, but a multitude of factors like road condition, grade, elevation, distance driven, humidity, etc. It's a completely different environment. The 2.2 turbo diesel may indeed not have enough power to get over any of the many 4000+ meter passes if it can't get enough air or cool itself while towing.
Relax And Recover for os level backups. https://relax-and-recover.org/
With rear you can back up your system to pretty much anything. Mounted volume, USB drive, even to a bootable iso.
I use weekly rear backups for my system, and hourly Borg backups for diffs/point in time restore of user data, but you could use rear for an entire system snapshot as well.
Managing a legally procured library of media. Piracy is not the only way to get digital music, movies, and books.
Export controls or legal compliance, most likely. Export controls because the code may be a protected technology, or compliance because the company doesn't have gdpr or some other legal framework.
I just unplug the mouses USB from the PC and plug it back in after putting the PC to sleep. Et voila, pc no longer wakes from mouse.
Web rings were one way someone would find their way around the Web before search engines really were any good. Basically, a group of sites of a certain interest would static link each other on each site.
Say you were on a web forum for skateboarders. That forum would have a web ring section, usually in the footer or one of the gutters, of links to other sites related to skateboarding. Each of those sites would reciprocally list the others as well.
If you published your own Website about skateboarding, you would email the webmasters of those sites and asked to be added; although some had centralized Webmasters to manage the ring.
REAR Relax-and-Recover will do entire system point-in-time snapshot backups to a bootable iso or physical USB thumb drive: https://relax-and-recover.org/rear-user-guide/index.html
I use rear for backing up my root, and Borg for packing up user data (for versioning, file recovery), but you can use rear for the entire system too.
To directly answer your question, what you need to run Jellyfin is a computer with sufficient CPU, RAM, storage, and networking. Many NASs can fill this role as can Single Board Computers (e.g. Raspberry Pi).
The QNAP you listed here doesn't seem to have Jellyfin as an app, but it does have Plex. You can find this information on the manufacturer Website.
Hardware: https://www.qnap.com/en-us/product/ts-233
Apps: https://www.qnap.com/en-us/app_center/?os=qts&version=5.1.0~5.1.3&II=616
The type of hard drive required for this NAS is 'internal', what you have linked as your hdd is an external USB drive, it wouldn't work the way you are intending. You need an internal SATA drive. Two would be ideal.

With a 4-core ARM cpu and 2GB of non-expandable RAM, I'm not convinced it would be a good Jellyfin experience. It could at first, maybe for one user at a time; but if you wanted to expand its capabilities (eg. have two streams at the same time), you might not be able to. YMMV
Rather than this QNAP unit, you could go with something that has expandable RAM and the Jellyfin app available to the OS. As mentioned in other comments, Synology is a well-known brand with lots of community support.
Hardware: Synology DS224 https://www.amazon.com/dp/B0C6927XPX/ref=twister_B0CLWLQCT6
Internal SATA NAS drive: https://www.amazon.com/Seagate-IronWolf-Internal-Hard-Drive/dp/B084ZV4DXB/qid=1700590050
Which very nearly doubles the price of the QNAP, but has expandable RAM up to 6GB.
If you're willing to learn a little bit of Linux and CLI, for the price, you can't beat a Raspberry Pi 8GB. It already has more RAM than either of those units can provide, is cheaper to boot, and would use the External HDD you selected. There was a shortage for a couple years with COVID, but with the release of the RPi 5, these are becoming available.

There are MANY guides on setting up Jellyfin on Raspberry Pi, like this one: https://pimylifeup.com/raspberry-pi-jellyfin/
Podman-compose is a python script that simply converts a compose file to 'podman run'. It worked fine enough for me, but the caveat being it doesn't have full feature parity and the errors aren't as good. The only thing I couldnt get working was connecting my GPU to jellyfin.
Turning conainers into systemd units is easy: 'podman generate systems --new --name $container_name › $HOME/.config/systems/user/$container_name.service' 'systemctl --user enable --now $container_name'

Altitude has a significant affect on engine performance [1], regardless of your opinion on transmissions. Conventional wisdom dictates declining carry capacity per altitude gain. "Note: For high altitude operation, reduce the gross combined weight by 2% per 1000 ft. (305 m) starting at the 1000 ft. (305 m) elevation point." [2] As does incline, which if you read my comment carefully you will notice I mentioned.
I'm not sure you're an authority on what folks in the American Midwest are or are not towing with cars, but I will note that automobiles in North America have one rating, nationally. There's no regional tow rating for Rockies vs Flats, or cold weather performance in Montreal vs Florida.
As with most all things in life, the answer lies in a complex host of variables, not just one singular difference. Just trying to be informative, there's no need to be defensive.
