Not to be critical, but the homelabs I find truly impressive are the objectively unpretty ones. Those that resemble the OpenBSD build system - a menagerie of servers haphazardly racked in a basement, Ethernet cables strewn about, and a questionable UPS setup that might get a second glance from the fire marshal. It's a lab, not a museum piece. Even Apple's labs look more like any other thrown-together engineering lab than something for public consumption.
