Its less of a need for powerful hardware and more of a want.

I started off my days with a laptop that had a broken screen. I took screen off and hid it behind my desk, worked perfectly fine, even came with a built in backup battery too xD

It really depends on what you're trying to do. At the end of the day, the foundational components are pretty standard across the board. All machines have a CPU, motherboard, storage mechanism, etc. Oftentimes those actual servers have a form factor better suited for rack mounting. They often have more powerful components.

But at the end of the day, the difference isn't as striking as most people not aware of this stuff think.

I'd say considering this is your first experience, you should start with converting an old PC due to the lower price point, and then expand as needed. You'll learn a lot and get a lot of experience from starting there.

If you already have one, it's a good place to start. However, power efficiency will be the biggest drawback. Power ain't free, and in some places it is very expensive. I'd recommend picking up some cheap ThirdReality switches and using them to monitor power consumption in Home Assistant.

There are a lot of ways to go. My own isn't particularly efficient, but it's an old rack mount server. Everything is built like a tank. It's robust as hell, and yet everything was well used and cheap. Probably not a good solution if you live somewhere with expensive power, but I don't.

My current home server that runs three dozen containers including Plex and Emby as well as two dozen other services and many terabytes of data is literally an old Lenovo desktop I got for free out of somebody’s garage 14 years ago. So yeah it’s sort of a perfectly fine place to start.

I started with my old gaming rig as a server, any decent intel cpu with quicksync is very good for plex and transcoding saving having to buy a cpu if you went with like a server grade cpu with no igpu

It depends on what you are running, but at one point I had an Odroid N2+ with 8GB RAM running Home Assistant, mpd, Snap server, zwavejs, mympd, jellyfin, and Calibre, all in containers, controlling the house and providing music for the sound system, playing movies, and with no issues. It ran for 7 years. So you don't need much; memory helps.

Oh - I take it back; after I put Jellyfin on it, it would struggle with transcoding. No GPU, old, weak CPU, whatever. But otherwise, it was fine.

At some point I realized I'd have to leave the computer with the house, because I have over 30 hardwired z-wave devices I'm not taking out if we sell, so I moved all of the services except Home Assistant and zwavejs to another computer.

My point is: old computers should be fine, assuming you're not trying to run LLMs on them. Or going heavy video transcoding. Just for serving up some web applications? You don't need much.

Generally speaking, yes. My home server is just a Pi.

Yes, a used PC can work great for a home server. Just don't go too old or it will be power hungry. Obviously you will want one with an integrated GPU to save power too. If you want to run jellyfin, make sure it supports hardware video encoding, preferably AV1 or H.265.

I think that's preferable. I have resused my old gaming computer as a server since I stopped gaming for a while.

It depends, but probably. I use 5-10yo laptops running Debian.

I started out with an old laptop then eventually "upgraded" to a refurbished office surplus desktop. I highly recommend starting out on a project PC as a sort of proof of concept before investing any money into it. Even hosting the family media libraries, I have never had an issue with streaming video, etc. even with pretty dated hardware.

I use a couple of old HP proliant mini towers. Relatively low power consumption, i7 CPUs and 32GB of RAM. I got mine from ewaste but it's the sort of thing you can easily find refurbed for the price of a high end Raspberry Pi.

Mine are lenovo thinkcentres, ypu xan get a good cpu, low power usage, up to 32GB RAM, one 2"5 drive + one nvme. Very easy to open and service.

Hardware requirements really depend on what you want to do with the server. I have a few raspberry pi, an old PC, and at least one or two old laptops to host things on. But really, I use the old PC the most. It pulls more power than a raspberry pi, but I've found it to be much more reliable and stable.

Drop some additional hard drives if you need a media server. More memory & CPU if you are doing things like manipulating images or transcoding video. I run a webserver and host various subdomains for things I don't want to pay to host. Plus working samples of my portfolio projects. I keep my actual portfolio on cloudflare, but link out to these work samples.

I also host some other apps that are just for my home network. Everything works great on a 10 year old PC sitting in a network closet. You are very likely not in need of professional server hardware.
