An intel N100 NUC is just a really good low power server platform and it will always be better for that than a pi.

The pi was never meant to be a server.

I never understand why people compare the Pi with NUCs. The latter is an order of magnitude more expansive (new, it’s hard to consider used stuff for serious work), has no GPIO built in, consumes way more power…

It’s in a whole other category.

Some people want to make a DIY equivalent of a Synology NAS - something to make backups to, and maybe some other light serving tasks. They don't need the GPIO, and they're not attentive enough to their power bill to appreciate the difference between a device drawing $3 a month and a device drawing $0.30 per month. They know many of Synology's products use Arm CPUs.

Later they find themselves saying hmm, it sure would be nice to have real SATA ports. Maybe a shared power supply for the drives and the CPU. It'd be nice to have enough IO and CPU to be able to saturate a gigabit link with encryption turned on. Oh, and a nice case with an active cooling solution built in.

Suddenly, a retired compact PC starts to look like strong competition.

If you use the Pi as a server it's not an order of magnitude cheaper than a cheap NUC. An N100 "NUC" like a Beelink S12 costs $150 including 16GB of RAM and 256GB NVMe storage! They are really ridiculously cheap. And really low powered.

If you want to use a pi as a server you won't get away with a slow microSD that kills itself every year, you'll need to add a real SSD (USB or now finally PCIe with the 5), decent cooling and power and a case. You will be at that $150 easily and you won't even have 16GB RAM.

I used to mess with little pi servers all over the place too yes. But this was in the days that PCs were power hogs. There's better options now.

That's not true at all. Pick one rated for the workload, eg A2 ("application" rating, optimized for random io) which can be had for < 15usd and you're not gonna run into issues.

> If you use the Pi as a server it's not an order of magnitude cheaper than a cheap NUC

I use my $15 RPi Zero as a git server[1], and it is literally an order of a magnitude cheaper at current prices. I bought the one I have for $5 (it was a promo, but still. That's how cheap Raspberry Pi's can get).

You'll need a good power supply if your Pi is destroying your SD cards. I lost a few before I wised up, and it's been years aince I replaced the SD card

1. Also hosts wireguard, has a bunch of webcrawlers and coordinates secondary backups between NAS and the cloud. It may not host docker containers, but the Pi is solidly in the "server" category for me, while consuming less than 1 Watt.

the NUC is a bad example. Plenty of used mini-PCs in secondary markets that can be had for sub-$100-150 price range with 7th-8th gen i5 or i7 CPUs. More I/O options than a raspberry Pi and beats a Raspberry Pi many many times over in performance. Including onboard media transcoding via QuickSync. By the time you add a power supply, SD card or add-on board for a nvme m.2 drive the price of the Raspberry Pi is going to be same as what a mini-PC with more hardware options and performance is going to cost.

Regarding lack of GPIO - if you're going to use it for a server, then not sure why GPIO is even needed. But if you need GPIO for hardware interfacing, then plenty of much cheaper boards out there than the raspberry Pi. Such as the dozens of different types of ESP32 boards.

As for power draw - yes, a mini-pc will definitely draw more power. I guess it depends on electricity cost at your specific location. I'm currently running about 25 containers on a HP elitedesk G2 with a Intel i5. On average it draws about 15-20 watts. It can go high as 40 watts when I'm streaming something from Jellyfin that requires real-time transcoding.

If you need GPIO you can just get an USB GPIO interface like the one at https://www.adafruit.com/product/2264

Yeah I didn't mean a NUC from Intel (who have just stopped making them anyway). I meant the Beelink kind of mini-PC or indeed some used systems which is exactly what I use, and generalised them under the term NUC. That was not very clear.

As I said above, used is not an option for anything other than a hobby. You found a great used PC for $100. Awesome, now get me 50 more of those with the same specs and price. And don’t forget to make sure every power supply, RAM and SSD is working properly.

You need 50 of those to run at home for selfhosting/homelab? I've bought a few. Never had any issues. They're not hard to find if you need them in bulk. But then again, most people don't need 50 of them or even more than a few for home use. Amazon renewed sells mini-PCs and you can just as easily return them if there are issues. If you need 50 of them, then your use case is for enterprise or business use. You should probably not look at a raspberry pi then either.

Even if you don't want to buy on secondary market because concerns around ram, power supply or SSD. Then even a new mini-PC running something like a Intel N100 for $100-150 will vastly outperform a Raspberry Pi 5- yet still provide better I/O options + QuickSync.

One example - https://www.youtube.com/watch?v=G3ZVYB2VmAM

I have a used m75q running 16 full blown windows server vms and a few Linux servers and it draws about 35w and cost me $200 all in with 2tb of m.2 and 64gb of DDR4 ram and it's still got room to grow.

I also ran a data center and an MSP where we always sourced used servers and never had issues with them running for longer than their intended 4 to 5 year lifespan.

I have pretty heavy workloads I run for side projects for friends and run everything on 3com gig switches I also got used. HP still warranties them and releases firmware.

Schools use off lease hardware other than chrome books that get beaten to death by kids without problems for years.

I really fail to see your argument against used hardware.

The pi ecosystem has become a total accessory one where you need non standard power supplies and video adapters to connect them up where a single used desktop PC gives more value and less points of failure - and when things do fail you can find readily available off the shelf parts to fix them.

I can see Nuc (like?) devices for around 100EUR, while a Pi costs me roughly the same.

What's wrong with used gear? Especially fanless hardware that's all solid state it should last 10 to 20 years without problems unless someone abused it and even then the wear part is the solid state drive at a reasonable price.

For some situations yes new and warrantied hardware is a non debatable topic but who is using a pi for mission critical stuff and expects it to be robust enough to not fail?

Of course, but if you are trying to do something which requires GPIO or want to build on top of Rapsberry Pi's other functionality (i.e. the cameras) your options are more limited.
