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?

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

    I for one prefer 19" rackmount stuff with disk bays in the front, but that’s more of a convenience than anything.

    UPS is nice, but it’ll work without it.

    I’ve had to deal with the Brazilian computer market and how it’s ridiculously overpriced due to import fees, so in your situation I’d just get any hand-me-down computer. Servers generally don’t require much unless you’re doing something special or intensive.

    Get your hands on whatever you can find for free or dirt cheap (laptop or desktop doesn’tmatter), install linux, and you have a basic setup that you can work with. If your use case requires more, then that’s something you can accommodate in the next iteration of your server.

      This.

      Almost all of my gear is bought used: switches, server, even memory. My main server is an old Dell C6100 blade server I got for $250. My disk array is a 12-bay SAN that I found for $50 and took a chance on being able to get it working. It’s power hungry but it’s got redundant everything and I have spare parts on the shelf next to it.

      I’ve been branching into ARM servers a little and right now I’ve got an RK3588 board with 32G of RAM. That’s new (and expensive for me) but I got a fibre channel array for $20 that I’m going to try to make work with it. $8 FC HBA and a $12 cable along with a $30 m2-to-PCIe adapter intended for eGPUs. I’m not going for speed here, but used data centre equipment is nice and some of it is dirt cheap because it’s too slow for “real” work.

    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.

    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.

        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.

          My Rx580 has basically been on continuously since I bought it in like 2017/18. I used it to mine when I wasn’t gaming until it became unprofitable, then to process sequencing data for my dissertation project while not gaming, and now it’s in my server.

    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.

    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.

    Had this link in my clipboard for a different comment but it fits here as well: https://hackaday.com/2025/04/09/self-hosting-a-cluster-on-old-phones/

    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.

    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.

      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.

    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

      If you are buying I wouldn’t get something older as the newer stuff is the same price often times because it is less well known.

        Gotta see some evidence on that claim. Older stuff is more power hungry no doubt about it, but especially old data centre equipment is waaay more reliable and built with some very nice creature comforts.

          Check the data sheets for the components. It should have a Average time to failure which will tell you about how long it will last.

          It might be fine but I personally wouldn’t rely on ancient drives

            oh I wasn’t talking about storage media. I’m talking about rack servers, switches, storage arrays (with new drives), etc., etc… The older hardware can wear out/break (I used to do MTTF/MIL-HDBK-217 calculations for avionics) but generally speaking it’s got a lot of life left in it by the time it hits the surplus market. It’s also usually designed with redundancies/failover mechanisms which means you don’t have to bodge together inferior solutions.

    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.

      That’s the thing, when I buy new devices, my old ones usually 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.

    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:

    • Ryzen 1700
    • 16GB RAM
    • GTX 750 Ti GPU
    • 2 8TB HDDs (bought for the server)
    • 1 SSD for boot (128 GB, just needs to store the OS)

    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. You probably don’t need anything fancy, your biggest requirement might be the GPU/iGPU if you’re planning to do transcoding.

    Intel i3 or i5 4th gen or newer will be solid.

    Dell, HP, Lenovo all make a ton of generic office PCs that are good for a home server, and you can find older models for under $40 in the US so hopefully they’re also cheap in Brazil.
