Sized for what goesin it next.
A rack gets built once and then lived with for years. It should hold the equipment going in today and the two things nobody has mentioned yet — the second switch, the recorder, the NAS.
- Wall-mount or floor rack chosen for the room it has to live in
- Patch panels and switches laid out in the order cable arrives
- Space left on purpose for what gets added later
- Enough clearance to get behind it without moving furniture
