I want to set up a home server and take advantage of everything it can offer, specialty privacy.
Raspberry PI, no matter the version, are all quite expensive here in Brazil, so that’s off the table. I’ll go for a regular desktop. But the the requirements for a server that “does it all” remains a mystery to me.
What specs do you guys recommend?
The joke is electricity and Linux.
The real answer is the free hardware.
My main reliable is from 2008? It cannot do modern virtualization due to not having the CPU instruction sets.
You might check if a simple CPU upgrade would get you there. I previously ran some 2005 Poweredge servers that came with a Pentium D processor, and it cost me something like $8 from ebay to upgrade to a Xeon and start running KVM.
What are you intending to run on this server?
If it is just PiHole, you can basically get the weakest computer you can find.
If you want lots of storage space, you will need to make sure you have a case and motherboard that will accommodate the drives.
If you are running encryption on those drives as well, you will need a CPU more powerful than what comes in a Pi, but nothing crazy.
If you are running lots and lots of VMs, you will want lots of RAM. A linux VM will use maybe a few GB each depending on what software each is running internally, a windows vm will use a bit more.
If you are doing AI workloads, you will need a graphics card.
Take a look at some N100 devices (or N95/N150).
These are a good alternative to RPis. Just be aware some of these are sort of haphazardly assembled so they might have cooling issues or bad power supplies.
Can’t say my Chuwi Larkbox X has any issues (other than missing a few QoL settings in the UEFI).
When I started my media server in 2020 I used e-waste from my building. Had an i7 3770, 16gb ddr3 ram and an rx460 graphics card. I ran jellyfin, ultrasonic and audiobookshelf for 10-15 people with no problem on this hardware. Anything made within the last decade should provide a good starting point for you.
This was almost my gaming PC specs in 2020. Rx580 and 16gb more ram. It’s now my server running jellyfin and immich for my family.
Rx580 was such a workhorse card. Used mine until a year ago and then it went to a friend who’s still using it today.
Keep an eye out for people trashing perfectly good desktop machines because Windows 10 is being retired.
If you want a server that “does it all” then you would need to get the most decked-out top of the line server available… Obviously that is unrealistic, so as others have mentioned, knowing WHAT you want to run is required to even begin to make a guess at what you will need.
Meanwhile here’s what I suggest – Grab any desktop machine you can find to get yourself started. Load up an OS, and start adding services. Maybe you want to run a personal web server, a file server, or something more extensive like Nextcloud? Get those things installed, and see how it runs. At some point you will start seeing performance issues, and this tells you when it’s time to upgrade to something with more capability. You may simply need more memory or a better CPU, in which case you can get the parts, or you may need to really step up to something with dual-CPU or internal RAID. You might also consider splitting services between multiple desktop machines, for instance having one dedicated NAS and another running Nextcloud. Your personal setup will dictate what works best for you, but the best way to learn these things is to just dive in with whatever hardware you can get ahold of (especially when it’s free), and use that as your baseline for any upgrades.
This. Be on the lookout for company grade PCs, like from Dell, Lenovo or Fujitsu, they come in small form factors, offer decent upgradability and are low/on power consumption and noise (most of the time)
You have to have an idea of what you’ll run on it first.
Old corporate desktops will do for a NAS and basic light services. Look for one that has three drive bays plus an NVMe slot.
Had this link in my clipboard for a different comment but it fits here as well: hackaday.com/…/self-hosting-a-cluster-on-old-phon…
In all honesty this may be a bit advanced depending on your experience and more importantly nerves, but any old PC/laptop can be turned into a server.
As for parameters I would suggest you go to the apps you plan on running and check their minimum requirements.
If you have an old android phone, then you can repurpose it into a Linux server.
Or an old computer. But you probably don’t need to buy anything to get started.
Link to guide to install a Linux server OS on Android device?
General Linux servers distros do not support android devices, you would need postmarketos.
The one you already have.
That’s the thing, when I buy new devices, my old devices go to my parents or for donation. So I have no old tech laying around, sadly. I’ll have to buy, that’s the reason for the post.
You dont have to buy new. Go to a thrift store and buy used if you have nothing lying around.
Find out if there are any corporate off-lease machines being sold in your area. USFF machines are frequently used as mini desktops or point of sale computers then sold off for peanuts when warranties are done. Especially look at i3-8xxx generation, as they don’t support windows 11 fully.
Any corporate fleet machines, really. Corporate C-suite executives always demand the best laptops on the market… They also demand the newest laptops on the market. This means there’s always fresh stock of last year’s corporate laptop hitting the used market. And they’re almost always gently used, because they just sat docked on some executive’s desk for a year.
Those $2000 laptops often get dropped on eBay for like $250, because the random Accounting person who has to auction them off doesn’t really care how much they sell for; They’re just checking a “was sold to recoup costs” checkbox.
How does one find such retired laptops? As an individual hobbyist in the US, would I just monitor eBay, Craigslist, or Facebook?
Yes. EBay and Amazon have a certified refurbished thing with warranties for a little more money, or monitor local classified sites if you can inspect them. I’ve bought a couple off Kijiji here in Canada, which is a bit like Craigslist and Facebook marketplace. The sellers didn’t advertise that they were a business selling off-lease stuff, but you can tell by the number of laptops they post.
One hundred percent go for USFF. Even the cheapest, most basic processor will smash server roles because it’s not having to power desktop applications, graphics, window managers, etc.
A computer. Seriously that’s it. Of course depends on your use case (media servers usually need more than a web host for example)
My current server is just my previous desktop PC hardware. $0 when you repurpose while upgrading your desktop.
For Linux: Anything Intel 4xxx is fine, later is better obviously. 4GB RAM is OK for one family, 8GB gives enough headroom to host NextCloud for a small office. SSD for operating system makes it snappy as fuck at the terminal but aren’t mandatory, slow drives for storage are fine.
Depends on what you want the server to do. A Minecraft server and a Pihole server have vastly different requirements. As a general rule, any old laptop or desktop will do, think on requirements for your grandma and that should cover most (except gaming servers) needs.
The minimum spec is whatever e-waste you can find that still powers on.
My home server has an i3-4160, 10 gigabytes of mis-matched RAM, a ten-year-old 240 GB SSD with 36000 hours on it, and three 1 TB hard drives in a RAID5 array each with ~25000 power-on hours. It runs Proxmox on the metal with a virtualized OPNsense, Nextcloud, and Jellyfin server (plus smaller services). Jank levels are high, but not fatal, and it was mostly free.
Living dangerously
I highly recommend you try proxmox to get the most potential out of you system. Basically can run many services and vm with little overhead, dynamically sharing the specs.
Now about those specs… what everybody else said really but heres some pointers:
You don’t need a big dedicated gpu unless your doing something that explicitly demands it. They are tricky to setup with virtual machines also.
If you plan on running a minecraft server i recommend at least 8gb ram. Anything else will probably run fine on 4. You can probably run quite a few things on 8gb but ram is cheap and its nice to have some extra room.
For cpu, the more things you do the More sense it makes to have more cores. If you plan on buying then amd ryzen x y z is you best option where.
X is the number you want higher Y is a number you should not care about as much Z is potentialy the letter “G” for graphics, they are often more expensive. Get them anyway because now you dont need a dedicated gpu (and even if you already own a gpu. Trust me you will thank me if that one ever has issues)
Go wuth what you have. Old laptop? Works! Old desktop? Also works! Old android phone? Might work! (VM/terminal)
If you have a device that can run Linux, start with that. Once you get some usage you can understand if you need an upgrade, and what kind. Maybe you will findout that this old laptop that you had works perfectly and you can sace money on buying a server.
Intel i3 or i5 4th gen or newer will be solid, and you can find older models for under $40 in the US so hopefully they’re also cheap in Brazil.
If you can find one of the optiplex desktops with the T version of Intel processor, those are low powered
I don’t think those really idle at much less power, so I’d take the performance of the normal variants
x86 will decimate most arm chips
Take what you have, start small and learn from it.
Old laptops are great, because they have low power consumption and even pretty used up battery will give you power redundancy.
Even a 10yo laptop is something with 4-5th gen Core cpu and that has plenty of power to get you started.
I use a random micro PC with Ubuntu installed. 2tb nvme, 16gb ram, not even sure what the cpu is
Raspberry PI
This also shouldn’t be your default option. Your default should be whatever you have laying around, and a lot of people have a Raspberry Pi sitting idle, hence why people use them.
What specs
That depends on what you want to do with it.
For example, if you want to host a video server, then you’ll want something that can handle transcoding. Check the Jellyfin docs for details, which recommends an N100 or better.
List all the things you need and want, and then look up what the requirements are. Basic file hosting is pretty light, so you really don’t need much (hence the Raspberry Pi rec).
I personally use an old PC with the following specs:
This is way overkill for what I need, but I had it laying around. You could even start with a laptop, you’ll just have limited storage (can get a USB emclosure of you want).
If you don’t have something, maybe a mini PC would work (minisforum, beelink, etc). Or maybe it doesn’t. I don’t know what you’re planning to run on it.
This specifically depends on what you want to run.
I’d say grab any unused PC in your home or off the street and it’ll work. Raspberry Pi are good for low wattage so it’s not expensive to run 24/7/365.
The electricity savings would pay for itself over time vs a 10 year old random desktop.
If the size and low power consumption of the Pi are what appeal to you, you can try a getting a used thin client. Lots of suggestions and specs here: parkytowers.me.uk
any old laptop with at least a third gen intel or something comparable works. you do want to get some extra storage via a cheap old hdd
I have a old optiplex 7010 with i7 and 8gig RAM. About 70€ on eBay. I upgraded it with a nvme SSD to bolt from (great tutorial here) and salvaged an old SATA HDD from an external case
Currently runs 11+ container in proxmox without issues. Way beefier than a raspberry pi. I also have room for 3 more hdds to put in a mergerfs system and 2 additional pcie slots für things like a faster LAN card or an additional SATA controller
depends on what you want to host. a lemmy or pleroma instance could run on an old laptop – that’s often where people start. a small minecraft server too. email can be a bit more resource intensive, but it’s not that bad. mastodon can be a pain in the ass. peertube’s main bottleneck tends to be upstream bandwidth. jellyfin doesn’t require too much power, but if you want to transcode a “decent” GPU is preferable. i threw my old 1650 in there and it works fine for a stream or two.
worth mentioning that any intel igpu from generation 7 (kaby lake) and up can handle 4k hevc transcode in hardware. i just upgraded my plex box to an i7 8700K and it works quite well.
oooooooooooo, shit
i’ve got an 8350k sitting around as an email server, might be time for some migrations! tho hwenc tends to be worse than sw (nvenc certainly is, but the performance makes up for it) so i might just keep it as is for now…
As long as it’s capable of booting into Linux, then you can start building a homelab…
Initially I had a 2-bay Synology NAS, and a Raspberry Pi 3B… It was very modest, but enough to stream media to my TV and run a bunch of different stuff in docker containers.
In my house, computer hardware is handed down. I buy something to upgrade my desktop, and whatever falls off that machine is handed down to my wife or my daughters machines, then finally it’s handed down to the server.
At some point my old Core i7-920 ended up in the server. This was plenty to upgrade the server to running Kubernetes with even more stuff, and even software transcoding some media for streaming. Running BTRFS gave me the flexibility to add various used disks over time.
At some point the CPU went bad, so I bought an upgrade for my desktop, and handed my old CPU donown the can, which released an Intel Core i5-2400F for the server. At this point storage and memory started to become the main limiting factor, so I added a PCI SAS card in IT mode to add more disks.
As this point my wife needed a faster CPU, so I bought a newer used CPU for her, and her old Intel Core i7-3770 was handed down to the server. That gave quite a boost in raw CPU power.
I ended up with a spare Intel Core i5-7600 because the first motherboard I bought for my wife was dead, so I looked up and found that for very cheap I could buy a motherboard to match, so I upgraded the server which opened up proper hardware transcoding.
I have since added 2 Intel NUCs to have a highly available control plane for my cluster.
This is where my server is at right now, and it’s way beyond sufficient for the media streaming, photo library, various game servers, a lot of self-hosted smart home stuff, and all sorts of other random bits and pieces I want to run.
My suggestion would be to start out by finding the cheapest possible option, and then learn what your needs are.
What do you want your server to do? What software do you want to run? What hardware do you want to connect to it? All of this will evolve as you start using your server more and more, and you will learn what you need to buy to achieve what you want to.
How complex is migrating the whole thing for a the new setup when upgrading? The best I can get with my current budget probably resembles the “quality” of your second server(first upgrade).
While on your firstly upgraded server, were there limitations to any of your self-hosting desires? Things that were only possible on your following upgrade? That’s my main concern. I’m probably over thinking things, it will be my first home server, I’ll probably stick the simple stuff at first.
Right now I want to host movies, photos, automatic backups, files in general. Also use it for the smart home that I’m slowly putting together, basic stuff… for starters.
As soon as I had migrated to a proper desktop (the i7-920), then it was a piece of cake upgrading. Shut the machine down, unplug, swap the parts, plug in, turn on. Linux has happily booted up with no trouble with the new hardware.
Since my first server was a classic bios, and the later machines was UEFI, then that step required a reinstall… But after the reinstall, I actually just copied all the contents of the root partition over, and it just worked.
The main limiting factors for me has been the amount of memory, the amount of SATA connectors for disks, and whether the hardware supported hardware transcoding.
For memory, ensure the motherboard has 4 sockets for memory, that makes it easy to start out with a bit of memory and upgrade later. For example you could start out with 2x 4GB sticks for a total of 8GB, and then later when you feel like you need more, you buy 2x 8GB sticks. Now you have a total of 24 GB.
For SATA ports, ensure the motherboard has enough ports for your needs, and I would also strongly recommend looking for a motherboard with at least 2 PCIe 16x slots, as that will allow you too add many more SATA or SAS ports via a SAS card.
Hardware encoding is far from a must. It’s only really necessary if you have a lot of media in unsupported formats by the client devices. 95% of my library is h.264 in 1080p, which is supported on pretty much everything, so it will play directly and not require any transcoding. Most 1080p media is encoded in h.264, so it’s usually a non-issue. 4k media however often come in HEVC (h.265), which many devices do not support. These files will require transcoding to be playable on devices that do not support it, but a CPU can still transcode it using “software transcoding”, it’s just much slower and less responsive. So I would consider it a nice convenience, but definitely not a must, and it depends entirely on the encoding of the media library.
Basically none. Grab whatever device you have on hand and install Docker on it.
As everyone have said, it depends on what you want to have in your server. I started with an old lenovo I bought in mercado livre for 200 BRL. It was a DDR2 PC with 4Gb ram. I bought an ssd and installed Debian. Used for years. After that I tried to build a DDR3 PC. Made it with 800 BRL and it’s decent to run my docker containers like an arr stack, nextcloud, VPN, reverse proxy and vaultwarden.

Anything that does the job is good enough. At its core a server is just a regular PC with a dedicated purpose. Sure, there are specialized hardware better suitable and purpose built, but it’s not a requirement.
