Hey,
I’ve build the infrastructure of a new hackerspace.

It includes:

• Virtualization (Proxmox)
• Firewall (pfSense)
• Reverse Proxy (nginx) with Let’s Encrypt
• Samba Active Directory, LDAP, FreeRADIUS (Univention UCS)
• Wireless LAN with radius authentication (TP-Link access point)
• Chat (Rocket.Chat)
• VPN (OpenVPN)
• Filesharing (Nextcloud)

The setup is designed to be cheap, easy to administer and open source.

Here is the link to the /dev/base wiki:
