There are many home labs...
But this one is mine.
CAT5e running through the house was terminated to RJ11 (phone lines) throughout. Reterminated to
RJ45 to the patch panel. Patched over to a Unifi pro XG 24 port PoE switch. It serves 3 WAPs in the house over PoE despite the CAT5e spec not officially supporting it. It has a 2x25 Gb bond with the Microtik CRS804-4DDQ-hRM switch beneath it. The Microtik is connected to the DAC breakout cables for the 4 sparks, 2 GX10s and 2 DGXs.
The other rack is just AV, and has a bit of cleaning up to do still. There's a MiSTer Pi on that 2nd shelf with the 4x10Gb managed unifi switch which is downstream from the main rack.
The server is a home built Unraid server with 142TB of total disk space, 120TB usable. Future upgrade coming to its NIC with its own QSFP connection to support an nvme pool for models along with my other media.
I'm also working on running more 10Gb to my gaming rigs (not pictured) for wired connections.
