I am currently using an old laptop (circa 2015) with a 250GB SSD in it, and 4GB of RAM. It runs Fedora 39 Server, and only hosts a Jellyfin instance through Docker right now (though I want to use Nextcloud later too). There is only 15GB of storage left on it, and the CPU is constantly overloaded (due to forced transcoding). I happen to have a lot of 500GB 3.5" HDDs laying around, and I want to use them in RAID 5. What hardware would be good for having 4 HDDs, and running Jellyfin and Nextcloud in Docker? I’m okay with either having just a 4-bay NAS (as long as it can handle transcoding (MKV 480p -> MP4)), or having a 4-bay NAS and a server/computer/NUC. I only have a budget of CAD$900 (USD$658 as of writing), but I am willing to go to CAD$1000 if absolutely necessary.
For lots of services that require little CPU and ram, I use tiny/mini/micro PCs, bought used. I get them for anywhere from $100-$400, and usually all I do is drop in an SSD. That includes Linux VMs when I’m testing distros or deployment on a distro, since 32gb ram on the host is more than enough to leave 4-8gb ram to the VM.
For some heavier applications, I also have a 4RU case stacked with drives, which I use as a third NAS (VM with drives passed through), large DBs, etc. Its just a 1700x with 64GB ram, and that’s plenty.
For most things (DNS, a few web servers, git, grafana, Prometheus, rev proxies, Jenkins, personal fdroid repo, homepage, etc) I just use the tiny/mini/micro’s. Imo, you can’t go wrong with those for your services, and a big case with spare parts and lots of drives for your NAS. Especially at the price you mentioned. Just remember you can separate your services easily, so don’t focus on getting everything in one spot, you can make your requirements (and cost) go up quickly.
