I’ve never done any sort of home networking or self-hosting of any kind but thanks to Jellyfin and Mastodon I’ve become interested in the idea. As I understand it, physical servers (“bare metal” correct?) are PCs intended for data storing and hosting services instead of being used as a daily driver like my desktop. From my (admittedly) limited research, dedicated servers are a bit expensive. However, it seems that you can convert an old PC and even laptop into a server (examples here and here). But should I use that or are there dedicated servers at “affordable” price points. Since is this is first experience with self-hosting, which would be a better route to take?
My server is always my old desktop hardware. It’s a 4th-gen i5 with 16GB RAM and it’s keeping up fine. I have thrown quite a lot of work at it too. If you avoid containers, you can serve 20 services off it no problem.
I too, was worried about power costs. Every time I do the maths, the new hardware will be obsolete by the time I make the money back in savings. If you’re concerned about environmental impact, the initial manufacture of hardware does more damage than running it over its lifetime.
Dedicated (1U rackmount) servers are always loud and power-hungry. I they idle at 130w and sound like a hairdryer that’s been left on.
Find secondhand on Facebook marketplace. Dive into an e-waste bin if you have to.
Absolutely yes. It’s better to use an old PC for a home server, because upgrades are cheaper, parts are easier to find, troubleshooting is generally easier, they’re usually more energy efficient than an older dedicated server, and you’re saving an old pc from becoming e-waste.
That being said, what you want to run on it determines how old/cheap of a PC could work for you.
Jellyfin works best when you can do hardware encoding, and these days that means throwing an ARC A310 in there and calling it a day. If you have a new enough processor, you don’t even need the graphics card.
Mastodon is pretty disk heavy, but if you’ve got a nice hard disk to put the Minio server on and an SSD for the db, you’re golden. That’s how I run https://port87.social/. It’s running on an old 6th gen Intel i7. The PC I built in 2015 (with a few upgrades).
CPU intensive servers like Minecraft are where you start to run into problems with older hardware. If it’s just you on there, a 10 year old CPU is fine, but if you’ve got a few friends, the server may start to struggle to keep up. I had to move my server off that same system I talked about above, because Minecraft was pegging the CPU a lot. But a 5 year old CPU would be fine for that. (Assuming that the 10 year old and 5 year old CPUs were both top tier CPUs when they were new. Like i7, i9, Ryzen 7, Ryzen 9. A five year old i3 would still struggle.)
Basically unless you’re trying to run AI models on it, cheap hardware is fantastic for personal servers.

Not sure how recently you ran this, or what all your were running, but in the past couple of years Paper has hit some pretty major milestones in unlocking threaded processing. Barring some sort of spammy 0-tick redstone nonsense or over the top plugins, I’d wager a Raspberry Pi 4 could handle up to about 5 or 6 friends without seeing any TPS dips. Its really remarkable how far they’ve pushed performance recently.
That’s really cool! I just run the vanilla server, but maybe I should check out Paper. Can it import worlds from vanilla?
Yes, it absolutely can, it’s super easy! Just swap your Minecraft .jar with Paper and it’ll do the rest. It’s a tiny bit harder to go back, but only marginally.
Out of the box, aside from huge performance benefits, Paper is virtually indistinguishable from vanilla, but it also opens the door to a whole world of easy-to-use server-side plugins.
Edit: (you should still make a backup before swapping, just in case)
That’s awesome! Yeah, I’ll definitely check it out. Thank you!
Wondering if you have and insight on power usage with the a310 in the system while idling. I built a sub 25w server and don’t want to mess that up.
Sorry, but I don’t know. I use an A380 in my system. I got it before the A310 was available.
How does the a380 impact your power consumption? If you have ever measured it.
I’d imagine not very much. I don’t know how to measure just the GPU. It doesn’t have any desktop installed, so it’s only ever rendering a console. It can transcode tons of 1080p streams at once, so even a transcode probably doesn’t draw much power. The CPU is the hungriest part, and that’s mostly idling too.
Thank you!
Heck yeah! Old desktops or laptops are how most of us got started.
Things to consider:
- Power- this will be on 24/7 probably. That adds up
- Speed- not just CPU, but RAM, disk access and network interface can limit how much data you want to move.
- Noise- fans can suck (pun intended). Laptops tend to run quieter
I’m sort of looking to upgrade and N100 or N150’s are looking good. Jellyfin can do transcoding so that takes a little grunt. This box would work well for me. It’s not a storage solution, but can run docker and a handful of services.
While laptop batteries may not have aged well, especially if they’re left discharged, one other nice perk is that laptops effectively have an integrated UPS.
Some laptops (Thinkpads in particular) are capable of limiting the battery level via a Linux application called
tlpso it doesn’t go pop when plugged in 24/7.
adding on to Noise, if you do end up in a situation where you’re considering buying refurbished enterprise hard disks, know that they are louder than normal consumer drives, esp if you have 4 of them running at once in a NAS
I wanted to echo this by saying that my lab stated as 4 bay Qnap NAS and evolved into repurposed consumer hardware as my interests and needs changed. My current server is an Optiplex that I bought for being small, quiet, and hanging lots of cores and my NAS is just my old gaming PC build with an HBA card (for extra SATA lanes) stuffed into a fancy case. A server is any computer that you say is a server (ideally one with functional network connectivity).
I’ve been running a plex server on an old desktop bought in 2016. Mostly streaming movies and tv shows to my family. I have a 2 TB SSD and a spare 2TB HDD. I was thinking about getting a mini PC to swap out the larger desktop. Could I get a larg HDD and ad it in an enclosure to the Mini PC to handle the media volume?

Like an external USB drive? Absolutely.
My answer would basically be yes, but. An old desktop (or even laptop) can definitely be used and will run fine. It should be very easy to get one for free or very cheap as companies will typically write them off after 3-5 years.
However, you might want to consider power consumption. Running a desktop 24/7 will use a lot more power than a new MiniPC or a NUC, so you may want to calculate how much it’ll cost to run a desktop 24/7 compared to a device that only uses 5W or whatever, and see whether the upfront savings make up for what you’ll pay in electricity over a certain period.
I think you might actually want to look into second hand MiniPCs unless you absolutely need to fit a bunch of hard drives in a case (like you probably would with Jellyfin).
Also I want to echo what others are saying about noise. A desktop or rack mounted server will make more noise than a laptop or MiniPC.
That depends. A lot of the power consumption comes from spinning media. Even very old desktop Intel chips have CPU throttling and consume very little while idle. Corporate desktops, even old ones, are usually quite economical.
A couple years ago my in-laws were downsizing after retiring and they asked if I would possibly have any use for their ancient desktop PC (at least old enough to have shipped with Windows 7).
I installed Debian on it and it’s running Jellyfin, qBittorrent through Gluetun, Calibre-web, NextCloud, and Pi-Hole containers, with plenty of room to spare. I’ve also got some services running on Raspberry pis (back when they were cheap). And an external 4TB hard drive connected to it acting as a NAS. No hardware transcoding or 4K video on Jellyfin but that’s no big deal for me.
All that to say yes, you can absolutely self-host on repurposed hardware. Any old PC you’re looking at is no doubt newer than mine.
Servers are just really big computers. I started off with a Chinese Raspberry Pi clone, then upgraded to an old mac mini + mini pc + a cheap cloud server (VPS). As you can see, you can turn any old computer into a server.
The cloud is expensive but reliable. Having your own server is cheap but it will go offline with every network fault or brownout. If you’re serious about self hosting I suggest buying a UPS.
Whatever computer you decide to use as a server, make sure it is quiet. When I first started, I tried to use an old 2010 aah workstation as a server, but the fans were so loud I couldn’t sleep, it was driving me crazy.
When talking about hardware, the physical computer itself, a “server” is commercial grade and designed to run under heavy loads for years on end with very high reliability. Error correcting RAM, redundant power supplies, room inside for huge processors, more airflow than a C-130 for cooling, etc.
On the software side, a “server” is just a computer that provides some service to users on a network. You very likely have one of those Wi-Fi router/ethernet switch things from the likes of Linksys or whatever, right? That is almost certainly acting as a DHCP server for you LAN, in that capacity it might handle kilobytes of data a day because dynamically assigning IP addresses on a household Wi-Fi network is not a very demanding task, so it’ll do it on a tiny little ARM processor with a few MB of RAM. It probably also has a web server, which is how the “go to its IP address in your browser and get to your router settings page” works. It’s serving a little website that most of the time gets absolutely zero traffic.
So, turning a desktop PC into a “server.” The question is, what services will it provide? Desktop PCs are pretty good at mostly low traffic with bursts of intense work, so if they’re going to sit still doing nothing while you’re at work all day, and then maybe handle some file storage or media transcoding during the evenings while you’re home, a PC will do that just fine, if you’re okay paying the power bill of having a computer up and running all the time.
If you’re hosting a website or a game server with a lot of active users around the clock, you might want to look into more professional hardware.

Honestly, that’s going to be pretty far down the road. Use what you’ve got, and fix issues as you go. Professional hardware is rarely needed, but it is pretty cool.
When I build my NAS/server last year, I bought a used Dell Optiplex from 2013 on eBay for $50. I tossed in an old SSD I had laying around, and squeezed in 42 TB worth of HDD drives. I added a PCIE SATA expansion card, and a 10 gig network card for 60 bucks to improve performance.
The only real downsides of doing it this way are
- No realistic way of upgrading hardware
- Limited space for internal drives
- No hardware transcoding abilities out of the box
- More power consumption than buying something newer
Generally speaking, yes. My home server is just a Pi.
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.
Any normal computer can become a “server”, its all based on the software.
Most enterprise server hardware is expensive because its designed around demanding workloads where uptime and redundancy is important. For a goober wanting to start a Minecraft and Jellyfin server, any old PC will work.
For home labbers office PC’s is the best way to do it. I have two machines right now that are repurposed office machines. They usually work well as office machines generally focus on having a decent CPU and plenty of memory without wasting money on a high end GPU, and can be had used for very cheap (or even free if you make friends that work in IT). And unless you’re running a lot of game servers or want a 4k streaming box, even a mediocre PC from 2012 is powerful enough to do a lot of stuff on.Totally agree, I’ll add that I run jellyfin, the *arrs, an admittedly low throughout ripping/encoding setup, and a few other containers on a single optiplex micro 7060 and there’s a lot of room leftover. I very much appreciate the laptop processor in it because it usually sits idle for 16 hours a day.
I love the vibe in this thread/community. You all seem like real cool cats. I appreciate that.
My home media server is an old nuc mini pc i5 16Gb RAM with attached usb storage running on a Linux distro, runs Jellyfin and a few other applications for the household.
In short yes, an old pc will work fine.
These also have the advantage of being nice and quiet, which if you are going to have it in your house rather than a hot garage or whatever can be nice.
I bought a NAS, later realised that it supported Plex and Jellyfin but it was often too slow to do the transcoding. I still use it for storage but there were no real upgrade options. It was cheaper to get an old NUC, rather than replace the NAS with a high spec one to be able to run Jellyfin properly.I’m doing a very similar thing with an old Dell thin client. I did inherit a large server from a company that was upgrading, but I’ve been thinking about downsizing a lot lately so now I use a few small computers on a 10 inch rack.
the best server is one that you already have
It is a fantastic idea to start your home server project on some e-waste hardware, and use it until you know specifically what features you’re lacking that you would need better hardware for.
Do it. Jump in. Just start with whatever you can assemble.
It’s a great way to keep your room warm.
