The U6+ will nearly max out gigabit with a 160MHz channel. The U7 Pro can provide higher speeds, but keep in mind there is only room for a single 240MHz channel on 5GHz. You will need 2.5G ethernet to take advantage of the higher speeds.
Interference from any other WiFi networks within your channel will slow things down a lot though. That makes running with channels wider than 80MHz difficult if there are any other networks in range.
My access points are AC Lite and and U6 Lite. Those are discontinued though.
If I get more for inside, I would probably get the U6+. I am also thinking about getting one of the AC Mesh access points for outside. I'm not too worried about speed since anything that needs high speed is wired. I don't have any neighbors, so I have all the bands to myself. If you are in an urban area, you should probably consider one with 6GHz support.
I use the Unifi access points. They work well and are fairly inexpensive. The management software can change settings on all of them at once, which is really handy if you have several.
Blurays are too small for backups anymore. It would take hundreds of them to backup all of my stuff. If you want long term backups, you have to spend a couple grand on a tape drive.
Usenet is a bit more work to setup than bittorrent, but you will be able to find lots of movies and TV shows there without having to seed anything. Unfortunately, you have to pay for access to good indexers if you want to download more than a few files per day.
I just use a zip tie. It keeps the bag shut and it's obvious if they open it. Of course they could potentially replace it with an identical zip tie. You can get security seals that are serial numbered if you want to protect against that.
It would be nice if they would make one with 4 or more LAN ports with at least one of them 2.5G and no WiFi. I need multiple access points to get enough coverage. The built in WiFi is useless to me since it won't integrate nicely with Unifi.
You can put a separate Wine prefix for each game on your NAS and use a launcher like Lutris to run the games. You can share the Wine prefix between multiple computers. Newer games that require a SSD probably won't work well over the network though.
