I used to have a 5700G system that I had to switch out to a 14600k system due to quciksync pass through.
I got my 14600K down to 55w from 75w with everything else being equal. Insane how efficient some setups can be.
My 16tb Pi sips at 13w max or 8w idle. But no encoding or enough storage for normal work. So it’s warm storage
If your PC has 32gb of RAM or more throw it away (in my trash bin) immediately.
My main application server is a middling office desktop computer from 2011. Runs dozens of services without a sweat.
And as usual everyone is saying NAS, but talking about servers with a built in NAS.
I’m not saying you can’t run your services on the same machine as your NAS, I’m just confused why every time there’s a conversation about NASs it’s always about what software it can run.
At this point you’re just fighting semantics. Even a commercial NAS is reliant on the software too, like with Synology. They run the disk management but also can run Docker and VMs with their built-in hypervisor.
OK. Science time. Somewhat arbitrary values used, the point is there is a amortization calculation, you’ll need to calculate your own with accurate input values.
A PC drawing 100W 24/7 uses 877 [email protected] $131.49 per year.
A NAS drawing 25W 24/7 uses 219 [email protected] $32.87 per year
So, in this hypothetical case you “save” about $100/year on power costs running the NAS.
Assuming a capacity equivalent NAS might cost $1200 then you’re better off using the PC you have rather than buying a NAS for 12 years.
This ignores that the heat generated by the devices is desirable in winter so the higher heat output option has additional utility.

But the heat is a negative in the summer. So local climate might tip the scales one way or the other.
I bought a two bay Synology for $270, and a 20TB hdd for $260. I did this for multiple reasons. The HDD was on sale so I bought it and kept buying things. Also I couldn’t be buggered to learn everything necessary to set up a homemade NAS. Also also i didn’t have an old PC. My current PC is a Ship of Theseus that I originally bought in 2006.
You’re not wrong about an equivalent NAS to my current pc specs/capacity being more expensive. And yes i did spend $500+ on my NAS And yet I also saved several days worth of study, research, and trial and error by not building my own.
That being said, reducing e-waste by converting old PCs into Jellyfin/Plex streaming machines, NAS devices, or personal servers is a really good idea
… 100W? Isn’t that like a rally bygone era? CPUs of the past decade can idle at next to nothing (like, there isn’t much difference between an idling i7/i9 and a Pentium from the same era/family).
Or are we taking about arm? (Sry, I don’t know much about them.)
Assuming a capacity equivalent NAS might cost $1200
Either you already have drives and could use them in a new NAS or you would have to buy them regardless and shouldn’t include them in the NAS price.
8 drives could go into most computers I think. Even 6 drive NAS can be quite expensive.
That’s not a NAS, that’s a whole-ass PC, though with only 8gb RAM. And way overpriced for the spec.
In the UK the calculus is quite different, as it’s £0.25/kWh or over double the cost.
Also, an empty Synology 4-bay NAS can be gotten for like £200 second hand. Good enough if you only need file hosting. Mine draws about 10W compared to an old Optiplex that draws around 60W.
With that math using the NAS saves you 1.25 pence per hour. Therefore the NAS pays for itself in around about 2 years.
my gaming pc runs at like 50w idle and only draws a ton of power if its being used for something. It would be more accurate to consider a PC to be 1.75x more power than a NAS but then account for the cost of buying a NAS. I’d say NAS would probably take 2-4 years to pay off depending on regional power prices.
I somehow doubt that.
My last desktop PC has been retasked as an HTPC. The CPU in it requires a graphics card for the system to POST, it’s currently mounted in a SFF case with barely room for two 2.5" drives, so it would either make for a shitty, difficult to service, bulky for what it does, power inefficient NAS, or I’d have to buy a new case and CPU.
My current machine is in an mATX mini-tower, there’s room for hard disks and the 7700X has integrated graphics so I could haul the GPU out, but it’s still kind of bulky for what you’d get.
So I’m gonna keep my Synology in service for a little while longer, then build a NAS from scratch selecting components that would be good for that purpose.
This is my rig, I already bought 20 30TB disks, how do I proceed?
Your system is a POS.
First choose a version of linux to install on it, then you can proceed.
Atm it’s running Proxmox, but I’ll go bare metal with a fresh install of Hannah Montana Linux, I want to do things proper this time!
I operate my hard drives totally external to my old PC’s case with a 3D printed holder keeping them together (with a little space between each drive for ventilation). It’s a little ugly, but it lives in a closet so I don’t really care how it looks. More importantly with my old Neatgear NAS I didn’t realize just how much speed I was missing out on. I guess with a modern Synology unit with a SSD cache you’ll likely get similar performance, but it’s so convenient to be able to run Docker containers and VMs on the same machine.
My UnRAID server is an HP desktop machine from 2011. More than capable of running dozens of services without tons of storage.
Highly doubt it’s worth it in the long run due to electricity costs alone
Depends.
Toss the GPU/wifi, disable audio, throttle the processor a ton, and set the OS to power saving, and old PCs can be shockingly efficient.
You can slow the RAM down too. You don’t need XMP enabled if you’re just using the PC as a NAS. It can be quite power hungry.
Eh, older RAM doesn’t use much. If it runs close to stock voltage, maybe just set it at stock voltage and bump the speed down a notch, then you get a nice task energy gain from the performance boost.
There was a post a while back of someone trying to eek every single watt out of their computer. Disabling XMP and running the ram at the slowest speed possible saved like 3 watts I think. An impressive savings, but at the cost of HORRIBLE CPU performance. But you do actually need at least a little bit of grunt for a nas.
At work we have some of those atom based NASes and the combination of lack of CPU, and horrendous single channel ram speeds makes them absolutely crawl. One HDD on its own performs the same as this raid 10 array.
Yeah.
In general, ‘big’ CPUs have an advantage because they can run at much, much lower clockspeeds than atoms, yet still be way faster. There are a few exceptions, like Ryzen 3000+ (excluding APUs), which idle notoriously hot thanks to the multi-die setup.
Peripherals and IO will do that. Cores pulling 5-6W while IO die pulls 6-10W

Same with auto overclocking mobos.
My ASRock sets VSoC to a silly high coltage with EXPO. Set that back down (and fiddle with some other settings/disable the IGP if you can), and it does help a ton.
…But I think AMD’s MCM chips just do idle hotter. My older 4800HS uses dramatically less, even with the IGP on.
I have an old Intel 1440 desktop that runs 24/7 hooked up to a UPS along with a Beelink miniPC, my router, and a POE switch and the UPS is reporting a combined 100w.
So I did this, using a Ryzen 3600, with some light tweaking the base system burns about 40-50W idle. The drives add a lot, 5-10W each, but they would go into any NAS system, so that’s irrelevant. I had to add a GPU because the MB I had wouldn’t POST without one, so that increases the power draw a little, but it’s also necessary for proper Jellyfin transcoding. I recently swapped the GPU for an Intel ARC A310.
By comparison, the previous system I used for this had a low-power, fanless intel celeron, with a single drive and two SSDs it drew about 30W.
Ok, im glad im not the only one that wants a responsive machine for video streaming.
I ran a pi400 with plex for a while. I dont care to save 20W while I wait for the machine to respond after every little scrub of the timeline. I want to have a better experience than Netflix. Thats the point.
Eh, TBH I’d like to consume less power, but I mean, a 30-40W difference isn’t going to ruin me or the planet, I’ve got a rather efficient home all in all.
I have a 3600 in a NAS and it idles at 25w. My mobo luckily runs fine without a GPU. I pulled it out after the initial install.
A desktop running a low usage wouldn’t consume much more than a NAS, as long as you drop the video card (which wouldn’t be running anyways).
Take only that extra and you probably have a few years usage before additional electricty costs overrun NAS cost. Where I live that’s around 5 years for an estimated extra 10W.

As I wrote below, some motherboards won’t POST without a GPU.

Yeah, and what’s more, if one of those appliance-like NASes breaks down, how do you fix it? With a normal PC you just swap out the defective part.
Most modern boards will. Also there’s integrated graphics on basically every single current CPU. Only AMD on AM4 held out on having iGPUs for so damn long.
I’m still running a 480 that doubles as a space heater (I’m not even joking; I increase the load based on ambient temps during winter)
A 486, eh?
I am assuming that’s a GTX 480 and not an RX 480; if so - kudos for not having that thing melt the solder off the heatsink by now! 😅
The GTX 480 is efficient by modern standards. If Nvidia could make a cooler that could handle 600 watts in 2010 you can bet your sweet ass that GPU would have used a lot more power.
Well that and if 1000 watt power supplies were common back then.
If they’re gonna buy a nas anyway, how many years to break even?
I started my media server in 2020 with an e-wasted i7 3770 dell tower I snagged out of the ewaste pile. Ran jellyfin, audiobookbay, navidrome, calibre-web and an arr stack with about a dozen users like a champ. Old hardware rules if you don’t use windows
And of course I see this after I bought (and received) a miniPC. Picked up a"beefier" n305 unit with 16GB and a 256GB NVMe, as I wanted some headroom in case I have loftier goals. So far have have horrible luck with it in the first 3-4 hours of attempting install of some Linux flavor. Started with Proxmox, as I want to run LXCs and containers of HA, PiHole, and Jellyfin, and there are some boots where I can’t even get past the installer. Booted up a LiveISO of Mint, and even that froze after a few minutes. Reading around about possible NIC driver issues, C-states, temperature throttling, etc… and what a headache so far. I can’t be sure it’s the device, me, or the images. /vent
I’m a rookie back in the Linux world after 15 years in windows hell, but Proxmox is hard if you’re new to Linux. I didn’t have the patience. I’d install mint on the nvme itself, let it get going, see if anything persists. Best of luck!
My NAS draws about 25w (without drives). Show me an old PC with 6 3.5” drive bays that draws 25w.
I’ve got a 12VDC Mini PC as my NAS/Jellyfin server with 6 SSD’s and no monitor that idles around 30watts and runs entirely off solar. It ain’t fast but it does everything I need it to do and costs zero dollars to run.
Those are good. I got tired of dealing with the unique trouble that comes of having drives attached with a USB JBOD. Also it was just a celeron and kinda melted doen if I ran motion detection with Scrypted.
At idle or under normal load? Im tempted to get the killawatt out.
Idle. Under load a bit more. It’s a mobile chipset, so it is efficient. Not as powerful as a desktop for sure but totally handles my basic workloads.
Ok. R5 3600, rtx 3070, and 4 spinning drives. Idles at 62W. 80W under normal load (2 concurrent streams). This is a hilariously over specced NAS. This is all 2nd or 3rd life pc parts (outside of the spinning rust), so financially speaking I’m happy with the result.
The long term goal is to use it as a homelab separate from anything I need to work all the time. I want to try running some LLMs locally and use it to control some home automation stuff. That’ll stress it.
Edit: so yeah its double yours.
How about a Raspberry Pi? I’ve got one (Raspberry Pi 400) running my Home Automation setup with a couple USB 3.0 ports. Was thinking there’s gotta be some add-ons for Home Assistant to put some external storage to good use.
Don’t need anything too fancy. Just looking for some on-site backup and maybe some media storage
IIRC raspberry pis aren’t great as big storage NAS due to limited io but like for a small amount of home storage more than adequate.
I’ve got 2 rPis - a pi5 running Home Assistant and a pi4 with a USB drive caddy acting as little more than a NAS (it also does all the downloading through radarr etc… )
I find them perfectly adequate.
My gaming rig acts as my emby server as it’s basically on all the time and it has a beefy gfx card that can handle transcoding.
For backups it will be fine. Same for media storage. But if you want media streaming from the device (like plex) then you’ll want something better.
Yeah, I guess I should have been clear that’s part of what I was thinking (although to be honest I’m mostly a schmuck who pays for a few streaming services and uses that)
What exactly would be the main choking point? Horsepower of the Pi to take that stored file and stream it to the client?
So I believe the Pi 4 was the 1st to have an actual ethernet controller and not just having essentially a built in USB to ethernet adapter so bandwidth to your HDDs/ethernet shouldn’t be a problem.
Streaming directly off of the pi should be tolerable. A bit slower than a full fat computer with tons of ram for caching and CPU power to buffer things. But fine. There’s some quirks with usb connected HDDs that makes them a bit slower than they should (still in 2025 UASP isn’t a given somehow) But streaming ultimately doesn’t need that much bandwidth.
What’s going to be unbearable is transcoding. If you’re connecting some shitty ass smart TV that only understands like H264 and your videos are 265 then that has to get converted, and that SUCKS. Plex by default also likes to play videos at a lower bitrate sometimes, which means transcoding.
There’s also other weird quirks to look out for. Like someone else was (I think) doing exactly what you wanted to do, but no matter what the experience was unbearable. Apparently LVM was somehow too much compute for the pi to handle, and as soon as they switched to raw EXT4 they could stream perfectly fine. I don’t remember why this was a problem, but it’s just kind of a reminder of how weak these devices actually are compared to “full” computers.
I think you can install OpenMediaVault on that, at least I used to run it on a Pi 3 and an USB drive. Then just run whatever docker container you wish to.
You can use it as a smb server and mount it with your other devices. They have an official addon for it with samba in the name.
I don’t know why yall are being so NASty… seriously what’s a NAS?
Network Attached Storage
I mean… my old PC burns through 50-100W, even at idle and even without a bunch of spinning hard drives. My actual NAS barely breaks that under load with all bays full.
I could scrounge up enough SATA inputs on it to make for a decent NAS if I didn’t care about that, and I could still run a few other services with the spare cycles, but… maybe not the best use of power.
I am genuinely considering turning it into a backup box I turn on under automation to run a backup and then turn off after completion. That’s feasible and would do quite well, as opposed to paying for a dedicated backup unit.
I see what you mean, and I have that (old PC with a bunch of 2.5" HDDs formatted as ZFS).
For me power consumption is more important than performance, so I’m looking for a lower power solution for photo sharing, music collection and backups.
My old PC locks up every 4 to 48 hours. It would make a terrible NAS.
My pc did that when my almost 10 year old SSD with my OS started to die. Switched it out and haven’t had an issue since.
How did you determine it was the SSD failing and not another component?
I used CrystalDiskInfo and it gave me a bunch of warnings when I ran it and said the overall drive health was “Bad”.
