I say “proper” rack because I was going cheap and didn’t realize this one uses threaded holes for mounting instead of the square holes + cage nuts like a big boy rack. (The uprights actually have the square holes on the sides, but the way it assembles, they are just about 1/2" too narrow to accommodate rack mount equipment)
Nothing too crazy… AT&T craptacular modem, Ubiquiti gateway, couple of switches, media server chock full of refurb drives, pihole to keep the ads away, and an ancient laptop for a console. But it was all scattered on some plastic shelving before… Now it’s at least on a wheeled rack where it kinda looks like I know what I’m doing.
Next step is cleaning up the cabinet above it, including a giant mess of coax cables lying in a heap 😅
Pro tip: if you’re not super fussy, search for AV racks instead of server racks. Many come with handy shelves and they seem to cost less, despite having the same basic functionality.
