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

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.

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