Ehh, sure. I'll bite.

From bottom to top:
Ludo - 13700k, 48GB RAM, RX7700 XT, running Arch Linux. Cloud gaming server, using Sunshine/Moonlight
Homelab - Ryzen 5600, 128GB RAM, Arc A310. Virtualization/container host. Services include FreeIPA, radius server, VM lab (virtual machines, eve-ng, etc. -- only permanent VM is a Fedora jumpbox), Jellyfin, Passbolt/MariaDB, PiHole and a cloudflare zero trust container for remote access.
(both Ludo & Homelab have an internal blikvm, as well)
UPS (650VA. Currently saving pennies to replace it with a 1500VA rackmount unit, which will go in the 2U of space at the bottom of the rack)
aging Synology DS220+, w/ 2x12TB hard drives. Also hosting a backup PiHole container. It's next on the list after the UPS, to be replaced with a rackmount NAS - most likely will go for terramaster 1U, and use the empty space in the rack for DAS storage as needed, but TBC)
drawer where I'm storing my spare cage nuts, patch cables, and longer ethernet cables
16 port tplink PoE++ managed switch. I want to replace it, but am having a hard time finding one that has all the features I want for less than $500 CAD - I'd need PoE++ w/ at least 50W of power delivery (preferably more), and want to have spare ports available for future expansion, so 16 port minimum. ignore the orange fan light - it doesn't like that I replaced the internal fan with a noctua that has a lower base speed than the original
patch panel where everything comes in/goes out
all in an enclosed rack, because cats like to sleep in warm places.
Not pictured: router, and wireless aps. because I don't really consider them part of the lab setup. suffice to say that they are all poe-powered off the centralized switch (and UPS), and they support enough vlans for me to keep everything separate.
no desire to go to 10gbe in home. really don't need it - don't move around enough big files often enough to justify the cost, and if I ever did take up a hobby that involved editing huge files, I'd install a DAC between Ludo and my NAS and do everything through Moonlight.
