I found an old 3u server chassis and put a regular atx motherboard power supply in it. 4 noctua 80mm fans and it’s relatively quiet for a server.
I bought one of those passively cooled router boxes from AliExpress and have been running opnsense for over a year on it now. It’s way overkill for router + ad blocking, but it’s been working great.
What’s the thermostat controlling? How is it wired up? I replaced mine with ram esphome with a temp sensor and a relay that bridges the pins when it wants to turn on. Mine is connected to home assistant but i think you can use esphome devices stand alone.
I did this for a while, but decided to just run opnsense on bare metal, I didn’t want my whole network going down if I had to restart Proxmox or something. It’s way overkill but it’s running opnsense, adguard and will soon be running ngnix hopefully.
My zfs cache for 6x 4tb drives in raidz2 is about 10gb of ram.
Bend the end of a zip tie into a U shape roughly the size of hole spacing and try feed it in one hole and out another.
