#2Surely one could make do with passive heatsinks on the Pis and use the back coolers?

#3What could you do with a similar setup? I mean: what's the purpose and/or the advantages compared to a "classical" solution ?

Its cool and fun and teaches you a skill at a low price point. There is essentially no functional reason to do this over a single high power server unless for some reason you need a bunch of ARM servers for something.

That may be difficult with the HATs on every Pi. They look like they limit airflow a lot.

The official PoE 'hat' (add-on module) comes with that fan, I believe that's what's shown.

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.
Recommended software: https://clusterlabs.org https://www.kernel.org/doc/html/latest/admin-guide/nfs/nfsro... https://wiki.gentoo.org/wiki/Diskless_nodes
Commercial advantage: Run highly cost and power efficient data centers, call centers, etc. Eliminate redundant state. Remove manual configuration rollout. Infrastructure as code. Full CI/CD with kernel-level control, per node, for any OS. Basically becoming a lost art in this day of "outsource to cloud". With SDN knowledge, confidently build your own cloud provider.

Clustering SBC's is a great learning experience, and makes for a great budget friendlier home lab setup.

#9Looks like fun ... but I am getting the new Mac Mini.

All fourteen Pis, even v4s (which are significantly hungrier), would be lower power (as in electrical draw) than even a feeble (as in compute power) traditional machine.
If you can distribute your workload (or it's not intensive anyway), i.e. having no single machine with a faster processor, then I think it's a good choice, cheaper to run.
Edit: I'm happy to be corrected if down-voters would like to reply... A Pi 4 draws 6-7W at full load. A former desktop PC turned server likely idles over 100W.
They're different beasts, so I'm not saying 'a Pi is better than a PC', I'm saying 'if your load could also be handled by a (bunch of) Pi(s), then all else being equal that might be better than the PC'. Of course all else is never equal, ymmv, you may already have the old PC, you may need very many Pis, so even if pennies cheaper to run it might take years and years to break even on the Pi acquisition cost.
