Hey, I want to dip my feet into self-hosting, but i find the hardware side of things very daunting. I want to self host a Minecraft server (shocking, i know), and i’ve actually done this before both on my own PC and through server hosts. I’d like to run a Plex server as well (Jellyfin is champ now it sounds like? So maybe that instead), but I imagine the Minecraft server is going to be the much more intensive side of things, so if it can handle that, plex/jellyfin will be no issue.
The issue is, I can’t seem to find good resources on the hardware side of building a server. I’m finding it very difficult to “map out” what I need, I don’t want to skimp out and end up with something much less powerful than what I need, but i also don’t want to spend thousands of dollars on something extremely overkill. I looked through the sidebar, but it seems to mostly cover the software side of things. Are there any good resources on this?
Media servers can be pretty demanding particularly when doing on the fly transcoding. Look for refurbished servers, big companies routinely toss perfectly good hardware as part of product lifecycle management. A favorite of mine is called 'techmikeny' although their site and search is pretty janky.
I/O performance needs to be considered along with the number of processing threads which really comes into play if you have a lot of virtual machines/containers running. Less than $1000 upfront and you can get well more than you think you need, and have space to improve. I'd say focus on CPU first, it's easy to add memory and storage later if you buy a big enough box to have extra slots open, but adding CPUs is more of a pain.
Electricity and noise should be a thought too. My largest box is using about 240 watts right now and if you go with actual rack servers they tend to be loud with a half dozen fans running at 6000 rpm or so. If you can stash it somewhere out of your living space all the better.
