Building a mini Homelab that fits in my carry-on

The article describes building a mini homelab that fits in a carry-on for a trip to VCF Midwest, where the author will demo NTP time history on vintage Macs using a GPS-derived NTP service on an Xserve G5. The build includes UniFi networking hardware (Cloud Gateway Fiber, Flex 2.5G PoE switch, 5G backup) and supports 1-10 Gbps networking, multiple WANs, and 12 Ethernet ports. The author shares first impressions of UniFi's ecosystem, noting its local-first approach and lack of licensing fees, but criticizes the lack of bootloader access and potential e-waste. The build was sponsored by Micro Center, but the author notes it aligns with other mini-rack projects.
