My beef with the Pi is that it's not just EUR40 for the device; you also need to add on:

- power supply

- quality SD card

- heatsinks

- a case

and then deal with

- non-x86

- thermal issues

- SD cards

- the CPU is too tiny to do anything useful anyway

Sorry to hear that X2x0 is expensive where you live. I find that the small additional investment over the RPi is worthwhile.

Ha. My home server for a very long time was a RPi 3B+. Totally fine for all kinds of background home server-y tasks, including running a local jupyter server for one-off calculations. (When I need a lot of cpu for something, I probably need a beefy gpu, which is a whole other beast.)

Power supply: It's USB powered. For a home server, I find it convenient to plug it into a USB port on the router, to which it is also connected for ethernet.

SDCard: It was set up to only use the sdcard to boot and use a USB stick as root, which gets around all of the sdcard issues. This is not a totally plug-and-play experience, though. My understanding is that the newer firmwares finally allow direct boot from USB, though.

Case: You can DIY it easily. The case for my home server was basically a folded piece of cardstock on which I drew a picture of a once-bitten pear. Other times I've used legos or dremel tooled altoid tins.

Heat sink: Unnecessary prior to the Pi4. (which also ramped up the cpu and power usage quite a bit...) They keep producing the older models, so it's mainly a matter of picking where you want to live on the compute vs heat management scale.

You forgot to add the extra power consumption of a laptop vs a pi. It adds up.

You do?

Heatsink and case were totally optional in my experience (or a case would make thermals worse). Power supply maybe, if your phone charger did not already work. SD Card or flashdrive; I have many of these lying around.

There is something to be said for having keyboard, pointing device and screen included with a used laptop, but the stuff you list it seems you just don't actually need.

Curious what workloads you're intending to run on the RPI that you find the CPU is tiny.

Granted, the RPi2 had a slow CPU, but I am finding the RPi4 is snappy enough for "serve a website out of a docker container" workloads. I am hitting SD card I/O limits faster than I hit CPU limits.
