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?
You don't need to buy server hardware, although it is nice. Depending on where you live you might be able to buy some decent second hand server hardware.
If it was me, I would buy new desktop hardware. Here is a fairly decent server that will do almost anything: Go for around 16 or 24 core CPU with high Ghz per core. 64GB or 128GB DDR5 RAM. Your most important factor will be storage speed. Go with NVMe drives. You have some choices here. JBOD: One or more independent M.2 key drives. Software RAID: Use your CPU to manage the RAID configuration. Hardware RAID: Use a RAID controller HBA card to manage the RAID (faster but single point of failure). Use RAID 1 for data protection (can lose one drive and still have all your data), RAID 0 (double the speed of your drives), RAID 10 (best of both but needs double the drives). Choose a motherboard that suits your choices.
Things to take into account: If you go with a RAID controller card, make sure that the PCIe lanes it uses can take the full speed of your RAID configuration or you might be bottlenecked there. Choosing an Intel or AMD CPU doesn't make much difference. If you are not good with linux distros and don't want a learning curve, stick with something like Ubuntu LTS 22.04 server. You most likely won't need any graphics card, but it depends what you want to do.
You can run a minecraft server on an old laptop, so these specs might be overkill, I just put what I would get and it will do almost anything you want to do with it. An 8 core CPU, 16GB RAM, with 1 NVMe drive will also be capable of all your described needs just fine.
