With this many pis, what's stopping you from buying an old workstation that can run all of those systems concurrently?

Management simplicity, probably. There are many pre-made images you can just flash on an SD card and have run perfectly. Computationally you could very likely run all of the services on a single Pi just as well.

Not doing this yet for lack of a Pi 4 (or other SBC with USB 3.0), but I plan to build a simple and reasonably performant NAS with one and USB SSDs.

I've considered PCIe -> SATA adapters, the boards that do this nicely aren't available - Radxa Taco, Wiretrustee SATA board - or have too few slots - PiBox- and the performance gain, about 30%, doesn't seem worth it when accessed via the network anyway. Of course I'd love to be corrected (hey Jeff).

one for each of the following

- Pihole

- Apache, subversion (proxied through Traefik on a 3 node x64 Docker Swarm cluster)

- NodeRed, MQTT (ESP8266 temp / humidity probes various locations around the house, running since 2017)

- OctoPrint for PrintrBot (3D printer circa 2015)

- OctoPrint, Klipper for Ender 3

Also, a 4 node K3s cluster each with 400gb ssd and 2Tb seagate managed by Longhorn

apparently I don't know when to stop :-)

> Raspberry Pi Zero 2W: ham radio-related software for portable use (e.g. WSJT-X, etc.) using cell phone via WiFi as display/input via RDP I would be interested in a write up about this or hearing more. I let my HAM lapse, but recent got into GMRS. No test required for the license, and way more 'simple'.

The very basics of it are that I'm trying to operate portable using HF (The simplicity of GMRS can be good, but for me I rarely use a radio to talk locally on repeaters. I like the idea of communicating as far as possible on very little power (QRP) with a small footprint, and the experimentation angle of it all.

Most of these live in different locations, or are portable.

I use mine mostly for educational pursuits. For example, I have a clusterHAT with a bunch of Zeros on it, which I used to learn MPI. I also use a pi as a home central server, and other pis for related things around that. I actually love using the Pi4 with 8G RAM as a desktop with two monitors. I'm not a gamer, so I don't feel any lag. Lately I've been re-learning a lot of my old electronics project material with the…

Does it actually work as a desktop? I heard it can't even play youtube vids witout lag

Sorry, I missed this. Hopefully you'll see my reply.

Lag certainly was a problem for me with earlier pi models as well. The Raspberry Pi 4 doesn't have the lags, or at least I don't experience any. It's actually smoother than my laptop with YouTube videos. And it's quite fine with both hdmi ports in use. Probably not multiple videos at one time, of course.
