But what about the heat sinks / fan when you mount the m2 on top? Especially /w Pi 5, to get more perf out of it, it presumably should have a sizeable heat sink complete with the fan?

The Active Cooler part (that contains a heatsink too) fits well under the HAT.

The fan won't do much if there a second PCB stacked right on top of it though, unless there's cutouts for it.

I do still think it’s a bit naff that the M.2 HAT+ doesn’t fit in the official case but I won’t re-open that can of worms. An rpi5 plus M.2 hat plus a branded ssd and you are well into the realm of Intel N100 S…

Yep rpi5 does not make sense anymore. N100 goes for $110 on sale with 512gb nvme/16gb of ram/psu/case all included. It completely roasts rpi5 while staying with x64 Linux.

Power consumption is a good contender for reasons to stick with rpis. The rough, quick search numbers I'm seeing for idle power are ~6w for the N100 SCB and ~1 to 2w for the pi. Max performance is like ~15w to ~4w.

Depends on where you live then. My home state of Minnesota has electricity for 11 cents per kWh, with only 19% coal.

Very different than, say, Germany. Power efficiency becomes a much lower priority.

It would be cool to have a nex gen RPi (perhaps even the Zero edition) that does away with the micro SD slot and replaces it with a built in NMVe one. In addition, replace most of the other ports (microUSB, etc...) with a number of USB-C ports.

Well, not an NVMe maybe (yet), but at least a built-in eMMC slot.

A covered fan is not very clever and the rp5 need active cooling.

Wait, which raspberry pi are you talking about? Max performance on a rpi5 is closer to 20 watts technically, and a bit less than that usually because of thermals. But it's not 5 watts, at least nothing I've seen indicates that. The official rpi5 charger provides 5v5a, so 25 watts. And a lower power mode is used when a "standard" 15w charger is used.

Earlier quoted context omitted.

We are starting to see SBCs that bake in an RP2040 to drive some GPIO pins (without needing to tie up a physical usb port), which seems like a reasonable compromise... I do like the RPi Zero size/perf/price combo, but for anything that needs more horsepower it's hard to argue with the bigger NUC-a-likes.

Yes there are N100 SBCs including a RP2040, so best of both worlds.

It’s not quite as seamless though, sadly, it’s just the same as having a Pico plugged in via USB but it’s a good step, even if the X4 (assuming that’s what we’re referring to) has some other flaws!

It does quite enough. Some test results are here: https://bret.dk/official-raspberry-pi-m-2-hat-review/#Temper...

And for any moderate use cases the need for any cooler at all could be disputed. I bet most RPi use cases don't include heavy computing.
