Hello /c/selfhosted!
Im sorry if this is not the place to ask but i figured id give it a shot. Mods feel free to delete if i should post elsewhere.
Im currently contemplating building an actual home server. My problem is i have no idea what to prioritize in a server. My main concern is probably power consumption and price. It doesnt really need to be a brast. I currently self host a media center on my gaming rig which id like to move over and id like to be able to host stuff like Immitch and maybe some game servers from time to time.
Im fairly confident in my building skulle since ive built a fair share of gaming rigs over the years but i dont really know whats optimal in a server setting. So i come to you to ask about this landscape.
Im thinking good amount of RAM a fairly recent AMD processor on an unspecified motherboard. I do have an M.2 and extra HDD lying around and also an old GPU (GTX 960) but idk if GPU matters. In any case, how would one go about reducing power consumption, my first idea was underclocking the CPU even though i know AMDs recent CPUs should be pretty efficient. But is there any other, better, solutions to bring down idle consumption?
As stated im pretty fresh on this. Closest ive gotten to a home server is a couple of RPis. Any information or tips are very welcomed!

As people have said, the Intel CPU with quick sync will be much better on power.
You could also use your m.2 to caache your regular hard drive with BTRFS and LVM or something like https://bcache.evilpiepirate.org/
Maybe spin down your HDD when it’s not being used. Most of your power savings are going to come from not transcoding unless you need to, transcoding efficiently when you need to, and powering things down when you don’t need them.
In Linux you can mess with your clock regulation, probably even put the box to sleep when you don’t need it, maybe wake on lan.
If you can live without the dedicated GPU for the media center, you can get an Intel CPU instead, which have QuickSync for media transcoding. It will use a fraction of the power a dedicated GPU does with the same workload.
That’s likely the place you can gain most power effeciency.

I’m running a media/back up server for 4 households on a single n100 mini pc and a couple USB drives. It’s a “good enough”, low cost, high wife acceptance factor entry point into self-hosting. It’ll happily age into a firewall if I want to build a better box later on.
It’s revealing what I do/don’t need vs what I want. It’s teaching me what people use, what they don’t and where I might want to go in the future.
If I could go again I’d probably get a n100 2Bay Ugreen thing. Then it’d age into a local back up and I wouldn’t have to deal with USB drives.
If you have old parts, use those, it’ll probably overkill. Most server stuff isn’t very resource intensive, so a little goes a long way.
If you’re buying something new, I’d recommend something small, like a Mini PC or an N100 rig. 16GB RAM is probably enough, and anything with more than 4 cores is probably overkill. A dedicated GPU is unnecessary, something with a modern-ish iGPU will be plenty to transcode video.
Using recycled parts is the best advice. As you said, it’s almost certainly overkill and the price can’t be beat.
I don’t recommend buying a discrete GPU. For home-level hardware iGPU systems like Strix Halo are much better than discrete systems. For example Strix Halo can run models that you need multiple 5090s for.
