So I am a total amateur, but i set up a TrueNas server that hosts my Plex server, then set up a linux VM to host a PiHole.

I also set up nextcloud vm on that machine too, i wanted to autobackup my phone pics and have a sync'd, shareable calendar with the family.

Nextcloud was the biggest pain in my ass and i never truely got it working as advertised. I ended up scrapping that part just because of how god-awful nextcloud was, and god forbid you try and update it to the most recent version.

The important thing I would look at is the idle power, because most of the time it will just sit the mre and wait for you to connect.

Dedicated NAS hardware is quite good with that, but there are nice DIY mini servers which are also very low power.

I don't see it as one OR the other. Nextcloud is not a backup. I would install unRAID or OMV with SnapRAID (both are good for later adding disks of any size) and Nextcloud as a container so you can access your data everywhere AND back it up! Remember (as someone already mentioned), the 3-2-1 backup rule.

As someone who is sort of tech savvy, but not savvy enough for Linux and all the trouble shooting that comes with it, would a Synology DS920+ be good?

Don’t forget the 3-2-1 rule with backups.

I'm running TrueNAS Scale and have nextcloud, pihole and jellyfin all running flawlessly as docker containers. They have a hardware compatibility list if you want to reduce/prevent flakeyness in your setup.

I'm working on putting together an unRAID NAS for media acquisition and storage right now. My initial plan was to use trueNAS scale, but from my research it's a lot less tolerant about adding drives to your array whenever you want, and I didn't want to drop a zillion dollars in HD space straight off the bat.

So far docker containers work well on it, and are relatively easy to configure. I'm planning to still leave my home assistant and associated docker containers on the orangepi where they live now though.

Raspberry pi can run homeassistant and nextcloud, but it probably runs better on more powerfull pc. Also having SATA or m2 ports is way better than USB for storage.

Deffo keep klipper on dedicated rpi. You need usb connection with 3d printer and cable cant be too long, it must be quality cable and you should guide it far from motors and other electronics. And not just because of a cable, it make sense to have a dedicated sbc for a machine that runs 5-50 h long jobs.

I went for DIY PC (cheap/silent/flexible) server and rpi4 for klipper. 1GB ram should be enough (I have 2GB) for klipper and you can keep your rpi inside of printer enclosure. I have mine with no fans and enclosure goes up to 40 C, no problems so far. There are also cheaper boards simmilar to rpi, but I have no experience with them.
