I like this one, a little more expensive but makes the Pi into a NUC style SFFPC: https://www.waveshare.com/pi4-case-argon-one.htm Edit to add the fan is optional, so it can run fanless with no throttling.

looks cool, and the breakout board is nice, but they don't show how it attaches to the pi. it's aluminum yeah, but does it actually do anything for heat dissipation?

Scroll down that page, there’s a photo and description... “The Extension Pillars Makes The Aluminum Case Become A Big Heatsink”

Running a 6 node cluster of Pi4s at home now. Did some benchmarks. Long story short. USB thumb drive boot disks are better performance and cheaper than SD cards. Fans are completely unnecessary on a Pi4 with an aluminum heat shield style "case". They do run hotter than with a fan, but they will not be heat throttled with recent firmware.

Yeah, I recently spied the 4 node Jetson Mate carrier board on CNX that facilitates building your own Multi GPU cluster ;) https://www.seeedstudio.com/Jetson-Mate-Cooling-Kit-p-4784.h... They recommend Kubernetes for private cloud workloads. But I am wondering if there isn't room in the ecosystem for a new virtualization / containerization technology to orchestrate tasks on multi gpus? Have heard NVidia is developing…

That's a slick cluster in a box. I'm not sure which modules I'd put on it, though. Unless you harvest them from the 2 GB dev kits, the total price pushes up against a single Jetson Xavier AGX, which is a better value (and has an M.2 slot for an SSD).

This is so exciting. Is this type of "movement" (trend) likely to see data centers coming back on premises for enteprise markets? (ie. back from cloud)

I don't think this will have (or is meant to have) any effect on professional applications. This is just for the educational and cool factor.

Right now, yeah. But if this tech trend (miniature, low power, cheap, commodity) continues and we can run our apps on them ... it might be a game changer. No?

If you want to learn clustering with physical hardware, and you don't have the power and size constraints, you're better off buying some off-lease business desktops. These i3 and i5 systems with 4 to 8GB of RAM can be had for less than $100 each. When you're done with the cluster, you can likely sell them for nearly what you paid for them.

i think you will lose in the end this way if you actually factor in power costs.

Not when you factor in performance per watt.

Cloud vs. datacenter is entirely about administration, rather than hardware.

Hu no. "Low power" , "cheap" and "commodity" already describes retail computers since almost 30 years.

Why do so many people want to see a higher purpose in any fun experiment? Can't it just be that, a fun and cool hobby project?

Purpose: Learn linux clustering/diskless nodes. Advantages: Cheaper than conventional servers, limited physical form factor suitable for constrained environments such as apartments, luggage, etc. Low power consumption, suitable for mobile/off-grid/renewable.

You could rent a couple of 1USD/month VPS, or if really on a budget rent a bunch of containers with ipv6 for just a few cents

One issue I have with going the VPS route is that what I'm charged is often not what I'm expecting. I will use estimation calculators and figure my bill will be $25/month (which I get for a couple months) and then suddenly get a $120 bill. This has happened more than once and has had me loose all confidence in these services for hobby projects. I'd rather just buy a Pi cluster at this point.

You absolutely could. But you wouldn't learn how to build a system that recovers from yanking a power or network cable, wouldn't own it, and wouldn't be able to run it on your terms. You'd need a credit card with an American-run payments network to operate, with a declared identity and a bank account, for which a prerequisite is a few months of stable living and income in a particular jurisdiction, itself something l…

This sounds like some kind of fantasy; how many people without stable living conditions or without a bank account that can be processed by the US are concerned with...cluster computing?

"What about all the homeless Iranian Ferrari owners!" doesn't seem like much of a rallying cry.
