I think I had a look at most of them except Umbrel. Bit of a mixed bag for me and none of them struck me as outstanding. On paper I fancied Runtipi but I struggled to get that up and running even with Debian 11. Liked the inbuilt proxy servers but some of the apps I tried fell over so there was that. Some of them seemed a bit of a walled garden, for instance cosmos cloud provides constellation vpn, free for now but intends to charge for it later. Having commited you might find in future that transferring your containers might be difficult because of the way that they are created to work with the specific application. I decided docker and portainer was simpler for me. On a similar journey to create NAS looked at Proxmox,Truenas Scale and OMV. I’m coming to the conclusion that they’re nice but I don’t need the level of sophistication they provide. The GUI are nice but I could build on Debian or Ubuntu for my needs, mostly containers and the odd VM.
I use RPi 4 2Gb for Pi-Hole.
Just retired a broken 8th gen intel i3 laptop used for Jellyfin. Its replacement is a GMKTec G3 N100. 4 core 4 thread, single channel SDRAM, but 12th gen Intel which is capable of a wider range of encoding & transcoding. Came with 8Gb ram and 256GB Nvme. Cost Less than £100 on ebay. Jellyfin installed ontop of Debian & very pleased with it.
Currently running Truenas scale with smb shares to service local network.
Additionally VPN on router provides access to home network.
I have a few redundant Rpi’s sitting about now as I’ve consolidated and will be using more NUC/ MiniPC hardware in future. They’re just better value at the moment for me.
Not looked at HA seriously yet, but its part of the plan
