You don't need a 42u rack. You can run a cluster of Raspberry Pi's hidden in your basement ceiling rafters like me.
Short throw from that to this classic: > hm. I've lost a machine.. literally _lost_. it responds to ping, it works completely, I just can't figure out where in my apartment it is. http://www.bash.org/?5273
Interviewer: That's nice, but how much AWS experience? :(

I remember how surprised people were when I demoed a $200/month bare metal server outperforming by a huge margin RDS MySQL instance that they were paying something upwards of 16k/month. IIRC we ended up using it as a disposable replica for some non-real time but heavy operations.
Here's what the bare metal server didn't come with: API access for managing configuration, version updates/rollbacks, and ACL. A solution for unlimited scheduled snapshots without affecting performance. Close to immediate replacement of identical setup within seconds of failure. API-managed VPC/VPN built in. No underlying OS management. (Probably forgot a few...) I get that going bare metal is a good solution for som…
Honestly after discovering NixOS I have a new found joy of administering Linux servers. It's easy and painless, everything is declarative and versioned, and new machines can be set up for new projects or scaling in a matter of minutes. This "cattle not pets" mentality doesn't make sense for everything and is highly inefficient if the OS itself seamlessly supports immutable workloads and configuration.
When it comes to server admin, nothing is painless. You just may not know where you're bleeding yet.
The worst thing I’ve had to deal with recently is debugging some faulty RAM sticks and NVMe failure. Obviously hardware quirks are still at play and there’s not much that can be done there, but in terms of making life easier on the software side, NixOS and reproducible config definitely helps over traditional distros.

Woah, 42u, that's quite something! How many of those slots are you using? What kind of cooling do you have to have for that closet, and how is the volume for the rest of the house?
Not OP but you find a lot of these kinds of setups on Reddit. Check out /r/homelab if you’re interested. Even crazier is /r/homedatacenter where you’ll find dudes with full tape libraries and everything. Super interesting to browse through.

Racks are not that expensive, and are a very good way to keep things connected, powered, accessible and tidy. Heaps of Pis in rafters will quickly turn into a cable spaghetti hell tied into ugly knots.

Snapshots every 4 hours? That doesn't sound impressive at all. In 2022 that's laptop tier capability.
What on earth are you running on your laptop?
But in all reality, laptops are really, really powerful these days.
It is partly for this reason that I’m funding an invite-only community shell/pubnix system.
