Top server is off by one. Done it to give some ventilation since as you can see I have more than enough space in my rack!

No, just concrete in the basement

I have an old post on it https://www.reddit.com/r/HomeServer/s/gmqCltsetT

They are all the same. Running K3s. Bottom 1u dedicated for pfsense. Server with 12 bays and 8 days running truenas within proxmox. They double their duty as a k3s node as well. One with 12 bays got 32 cores(64 logical), so it got some horsepower. Two truenas systems replicate with each other for extra redundancy, and one got 6x20tb, and the other got 12x10tb drives. I wish there is a way to cluster truenas systems. At least for NFS and ISCSI 😭

IP cams, I got three APs. One dedicated AP to connect to my dash cam, Raspberry PIs(octo print etc), Lora gateway, other small poe powered switches, and finally, google fiber media converter. I love POE because it makes things so much simpler and very reliable. The best part is I can put a UPS behind it and expect everything to run indefinitely!

Yep, those datto are nice and cheap. I did the same, flashed asrock firmware, and I unplugged some fans in them. Never got too hot and very efficient!

It’s an LC to LC keystone. Behind the keystone, I have plugged into an outdoor rated pre made single mode fiber. That wraps around my house outside to my second floor. Why? I already had a bundle of wires going around the house, so I just made it worse by adding another 😁

I can saturate with iperf easily. Otherwise, 20G max in real life because of single thread performance issues
