I used to think of my old PC as “still useful,” which is a polite way of saying it was headed toward the tech shelf of retirement. It handled everyday stuff fine, but it didn’t feel like it had a second act. Then I finally listened to our resident Proxmox guru, Ayush Pande, and installed Proxmox. Now, my tiny Geekom Air12 Lite mini PC is something closer to shared infrastructure than a personal computer. Once it clicked, I stopped seeing limits and started seeing possibilities.
