Put a smaller box/table/shelf underneath the black table. Now you have three layers (floor, small table, big table) to put stuff. You can even add a tablecloth on top if you want to cover the stuff underneath. That will make it look neat and tidy for $0.

Parsec has the lowest latency of any large free remote view software.
You can get 10 ms round trip on LAN, which is less than 1 frame at 60 FPS. You need Intel CPUs with QuickSync Video or nVidia nVENC GPUs. nVidia has the fastest hardware acceleration of anyone. On both the client and host. A Raspberry Pi isn't supported by Parsec anymore. It's not the best choice for this type of thing. A $150-$200 mini pc would be the best.
The UPS on power outage will drop power to devices plugged into it.
Have you ran a Test button to see if the UPS works / battery works and actually provides power? A component may have failed inside the UPS, the battery may be bad, or the wire connection may be poor. Did everything work, tested with no power, with the previous batteries?
The UPS does not power back on when power is restored.
That's normally a setting that's configured. Staying off is safer, in case the battery didn't get enough time to charge back up and power immediately goes out again.
Used Dell Optiplex can be a good value. Can get 6 cores, an expansion slot, Intel QSV for Plex. Might not have space or PSU connections for HDDs, because most cheap, small PCs have SSDs these days.
A lot of the cheap mass produced PCs will have limited motherboard/PSU combinations. Even if they have a SATA port, they're probably not going to have multiple HDD power connections. You would run into that problem with the HP Elitedesk too, unless you got a new power solution.
The services all have different IP addresses. You setup your containers and virtual network to use multiple IP addresses on a single physical interface connection.
192.168.1.100:34000 is Plex

I can turn on my VPN and type any of them into the address bar to access them.
Put the fans on both radiators as intake, blowing inside the case, then exhaust out the top.
That way one of your CPUs won't be hotter than the other.
If you're number one concern is data integrity, you might think TLC vs MLC VS SLC matters. After all, storing more bits in an electron gate makes it easier for them to leak out and lose data.
The thing is, prices are getting so cheap on SSDs, that the cost to buy a brand-new replacement SSD is cheaper than spending extra on enterprise SSDs. If you're already practicing backups (which you should), modern consumer Samsung SSDs will provide the most reliability/performance per dollar.
Its more than enough computer performance for those tasks. If it comes with a case, memory, storage, etc. It's not a bad price. It has an Intel integrated GPU with QuickSync Video which is good for Jellyfin hardware accelerated transcoding.
