Nginx proxy manager, Heimdall Dashboard, Hedgedoc, Your Spotify, pwpush, unifi controller, dmarc reporting tools, zammad and vailtwarden.

I did that with a TP-Link RE655 WiFi repeater which has a LAN Port. Worked surprisingly well and I could even run some servers behind that setup.

Get a used PC, haswell or newer. Those can be found for less than 50 €. Upgrade it to 16 gb ram, install proxmox.

Setting up my own OPNsense router, setting up my own mail server (testing in homelab, then moved to DC as production), Univention Corporate Server as active directory for centralized authentication.

I’ve thrown out my Q6600 in 2020 and that was more than overdue. Deploying any Core 2 doesn’t make sense in 2023 since you can get haswell and newer generations fully built (office PCs) for < 50 €.

Fritzbox is great if you just need basic settings. Otherwise: used enterprise x86 firewall like sophos sg running opnsense/vyos/pfsense.

I run various haswell i5 hosts, one of them has 84 watts tdp.

i5 4460, 4x 4GB, 1x sata ssd, 2x dual port gigabit lan pcie card. Whole thing draws < 50 watts with 10 % cpu load.
