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 kWh@0.15 $131.49 per year.
A NAS drawing 25W 24/7 uses 219 kWh@0.15 $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.

Highly doubt it’s worth it in the long run due to electricity costs alone
brucethemoose@lemmy.world 2 weeks ago
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.

Stuff designed for much higher peek usage tend to have a lot more waste.
For example, a 400W power source (which is what’s probably in the original PC of your example) will waste more power than a lower wattage on (unless it’s a very expensive one), so in that example of yours it should be replaced by something much smaller.
Even beyond that, everything in there - another example, the motherboard - will have a lot more power leakage than something designed for a low power system (say, an ARM SBC).
Unless it’s a notebook, that old PC will always consume more power than, say, an N100 Mini-PC, much less an ARM based one.

And heat your room in the winter!
Add spring + autumn if you live up north.

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.

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.
BeardedGingerWonder@feddit.uk 2 weeks ago
Literally did this migration this weekend. Still need to install the A310 drivers and I don’t run Jellyfin (streaming handled client side with minidlna or SMB) but how do you find it?
leftascenter@jlai.lu 2 weeks ago
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.

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)
SlartyBartFast@sh.itjust.works 2 weeks ago
A 486, eh?
thatKamGuy@sh.itjust.works 2 weeks ago
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! 😅

If they’re gonna buy a nas anyway, how many years to break even?

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.
