I don't see the appeal of using these mini-PCs. Using an old second hand power supply is enough to turn me away.

And the PI has many advantages. Power supply dies? I can order a new one in literally seconds. And meanwhile I wait for it to arrive I can use a spare notebook charger or whatever. Etc.

The shortage sucked, but it is solved now.

Last image I created I tucked in a Raspberry Pi 1, and it worked just fine. The versatility is unmatched. Equally I can test an image at my home and then let someone install it on the other side of the globe.

The point of a Pi for me is more that you can have it where you need it. Attached to your TV or whatever.

For a home server I would recommend something beefier, an old desktop will be superior to any mini-pc and the Pi. But probably bulkier and more power hungry.

A Pi5 with nvme does work and be a decent home server for tinkering though. From my perspective the niche for the mini-PC is pretty much nonexistent.

But I don't think maximum utility is the goal though, it is a hobby. Do what you enjoy! Tinkering with low power PCs might be enough of a reason alone.

But these comparisons to the Pi doesn't make much sense to me.

> Power supply dies? I can order a new one in literally seconds.

For the RPi 5, for fully reliable operation, you need an oddball 5V/5A power supply, which is not actually a standard device. IMO Raspberry Pi messed this one up. At the price point, either use a barrel jack or support USB-PD for real. (The latter would be great for many use cases, because the same conversion circuitry would enable driving from a wide voltage range. A tiny cheap ESP board can do this — why not a rather pricey Raspberry Pi?)

  • It is part of USB-PD though, it is just a recent addition (PPS) that isn't that common yet.

    I agree it isn't ideal, but you shouldn't blindly buy a PSU to any computer. Extra easy mistake to make when it is USB-C though.

> Using an old second hand power supply is enough to turn me away.

It's a standard 19V laptop power supply. Any laptop supply will work with that HP device and they're just as easy to find as any other power supply.

Well for one, they have an normal HDD interface.

The worst part of a Pi is the SD card. It's truly the worst interface to use for booting off. Extremely unreliable and due to kernel bugs, having your system on an SD card is extremely unstable. (but that is more of a Linux issue than an Pi issue).

I found RPi to be unusable for anything remotely serious. Recently I got RPi 5 with NVMe hat. Had a lot of "fun" finding drive that will actually work with it, so more money and time spent. Got it working and found that it randomly dies after couple of days. The time and money spent I probably could be better off just getting one of those N100 mini PCs.

For dabbling with electronics Pico or STM32 seem more reasonable. RPi GPIO is too limited for anything that could use its processing power. Not sure if there are even any distributions that would support realtime operations with those pins or things like DMA, custom protocols working at 1x-1xx MHz speeds.

You can get new Mini PCs for not much more than a Pi 5, especially if you want an 8GB model, case etc. $150-$200 will get you an okay bottom barrel Intel PC with support for stuff like SATA and M.2 SSDs which are more annoying to have on the Pi.

  • And $150 is overstating it. Look up ‘n3350 all in one’. Lots of models and retailers selling these atm. Intel must be selling these cpus for a few cents given the price for these complete systems with storage ram, case and power supply is ~$65 even when not on sale.

    • N3350 is nearly ten years old and I suspect a lot of the ultra cheap "new" systems using it are actually using salvaged parts.

The mini-pc market for those HP machines is fairly in demand and you can get them very well priced.

They're fantastic as a low cost machine with decent specs that take up minimal room, they're also usually corporate devices in which there are plenty of drivers that work well out of the box.

I bought one to act as a home server and it works flawlessly running Proxmox, over the machine I built many years back which was slower and bigger.

I just think comparing the Raspberry Pi to these Mini-PC's is just a silly comparison to begin with.

I don't see what's wrong with old second hand power supplies. These corporate mini PC's are manufactured in such large quantities, that finding them in good condition from reliable sellers isn't exactly hard.

For most self-hosting purposes mini-PC's are often the best option in my opinion, because they're small enough in size and low in power consumption to be comparable to raspi, but powerful enough for stuff like running a virtualization environment, and support containers that are only for x86. Admittedly I did go for desktop though, because I wanted more storage, dedicated GPU and ECC RAM, but for lots of people a single mini-PC could host everything.

I still like raspberry pi for doing small things where I want redundancy, like running DNS server that stays up even when I do maintenance on my main server. And obviously it's great for embedded projects and such.

Everytime I used a pi the cabling ended up being a mess. A regular computer usually have all ports on one side only, and possibly additionnal usb / trs on the other side. On the PI power/hdmi/TRS is on one side, usb/ethernet on another, GPIO on another and more easily accessible from the top. This is my major PITA concerning the PIs.

In the end most of the gains made from the small footprint are lost because the actual physical footprint increase from the number of cables you have to attach to it from all sides.

I use two of them (Lenovos) in my small homelab. They take up 1U side-by-side so they’re great if you have limited space.

Suprise - you are not the ones who do.

This is a quite a stupid argument.

a) it's totally the same for any other PC: you just order another 'in literally seconds'

b) if you don't like a second hand PSU then order a new one in the first place

> And meanwhile I wait for it to arrive I can use a spare notebook charger or whatever

... just like you can have a compatible charger for a mini-PC ?[0]

> For a home server I would recommend something beefier, an old desktop will be superior to any mini-pc and the Pi

For most of the people there is no need in 'beefier', 32Gb RAM, 256-1024Gb SATA/NVMe is all they need.

> The point of a Pi for me is more that you can have it where you need it. Attached to your TV or whatever.

Anyone can have mini-PC where they need it. It's because they are mini, not a desktop ones.

[0] by the way, most of the time those mini-PCs have a notebook style external PSUs (not some anemic square brick of 15W) and they are quite rare to break

  • The argument was that you already have a PSU at home. Or in my small town I can get one in 15 minutes, or order it and have it delivered tomorrow.

    On the contrary, the notebook style external PSUs are more likely to break and much harder to find replacements to. When it has happened to me the best source to buy has been to order it from another country.
