I use whatever is cheapest at the time of buying. I just make sure they’re not SMR.

I can believe it! If it still works why change it? No need to reinvent the wheel!

Jellyfin is what I use now. I was using Plex for the longest time, but I personally feel like they keep moving away from their roots so I ditched them for Jellyfin for about 2 years now and it’s been great I haven’t looked back. I still run Plex, but it’s for a few of my users that refuse to move off it 🤣

Block 66 and it’s a been a lonnnnng ass time since I’ve punched down on one of those haha!

Given that you’re “most comfortable” with windows is probably the number one reason why you should go with something other than Windows. I think you should always get out of your comfort zone and expand your knowledge. Sure you can keep using windows but why but branch out! Hell if you really want to take a leap of faith load up TrueNAS core 🤣

Also the 9xx servers like the R930 you mentioned are 4U.

That UI is from Ubiquiti Unifi and more specifically he’s probably running a UDM-Pro or UDM Special Edition.

Letter determines if it’s rack mounted ® or a tower (T). First number is the model the higher that number the more higher end the model is. Second number arguably the most important is the generation or how old it is. Example being I’d take a R340 server over a R710. R340 being a lower model but newer and faster generation… hope that helped make sense.
