For normal use like that 16GB is generally just fine. Some games can use enough that you'll need to close Firefox and other RAM hungry programs though.
As far as needing more than that, people who do heavy design work or edit videos and that kind of thing generally do. For example 32GB running Fusion in Davinci Resolve can be a bit limiting sometimes with higher resolution or 10 bit footage.
That ones actually fine IMO because they advertise Mbps which is fairly clearly different from MBps (b vs B, bit vs byte), and very easy to convert between.
Yeah it sounds nice but too much time investment for me.
I can install PBS client on any system but it requires manual setup and scheduling which I don't want to do. When used with Proxmox that's all handled for me.
Also I don't think Proxmox cares about storage either, I just use ZFS which is completely standard under the hood.
I don't think I've ever had a quality brand PSU go out on me. Software RAID like MD or ZFS works fine on basically any hardware, and I wouldn't use hardware RAID these days anyways.
I used to worry about that stuff and use enterprise hardware, but its just so expensive for decent performance, and so power hungry.
Like try and match even a budget i3-12100 or similar for single thread performance (needed for game servers mostly) and you really can't with used enterprise gear. Plus that i3 has an iGPU that can handle a ton of transcoding tasks, and ML for stuff like immich search or frigate object detection. And it uses about 10w or less most of the time.
The main things that come to mind are you have to test/monitor 2 seperate actions instead of 1, and restores of single files could be more difficult since you need to login to the backup server, restore the file from a snapshot, then also copy that file back to your PC.
What happens if you accidentally overwrite something important in a document and save it though? If there's no incremental versioning you can't recover from that.
