I've bought a used Dell Poweredge T320 with Xeon E5-2428L (low consumption), 24GB RAM and an SSD, so it's quiet and cheap to run, and I've got Debian with dockerized services. jwilder/nginx-proxy to act as a reverse proxy that dynamically routes traffic to containers without manually editing the config, using subdomains, with SSL wildcard cert DokuWiki that I don't use much anymore Nginx to serve static files used by other servers My web resume Piwigo for pictures IoT: Custom Python Flask server that is used to control Philips Hue lights from ESP8266 wifi modules (cheaper than buying 20€ Philips switches) Vaultwarden (Bitwarden) my password manager, shared with family OpenVPN server Wekan (self-hosted open source Trello-like) Gitlab and Gitlab CI (created when Github didn't have free private repos, might delete at some point because it uses some CPU even when idle, but I have over 50 personal repos, also share with close family) Nextcloud, but I don't use it for important/sensitive stuff yet, I'd have to set up a robust backup procedures Other experiments, like openvscode-server, web interface with password to trigger wake-on-lan for my PC, etc. Email seems like a pain because small servers are always seen as spam by big services, need to manage reputation, too complicated, so I use my hostname provider (Gandi) SMTP relay to send email, and I could set up a free inbox too, but I don't need it.
