Mac mini cluster in a 12U 19 inch rack
Eight Mac minis in two 4-bay 3U rows and a Mac Studio, under a 24-port switch with a UPS at the bottom.



Most mini PCs, Macs, modems and small switches can't go in a rack on their own. When you add one, the planner puts it in a rack mount made to fit that exact device, from 3D Rack Mounts. Gear that already has rack ears goes straight in.

How it works
- Pick a rack. 10" mini racks (DeskPi, GeeekPi, Lab Rax and similar) or a standard 19" rack, at the height you have.
- Add your gear. Search a device to place it. Gear that already has rack ears, like UniFi and Netgear switches, Synology RackStations, UPS units and PDUs, is in the list too and goes in as rack-ready.
- See what's missing. Anything without ears shows as "needs a mount", with a mount you can buy for it.
- Share it. The link holds the whole layout, so a build can be posted, compared or finished later.
