For front and back clearances, I go with however deep the cabinets are as 
a minimum.  If the cabinet is 40" deep, you'd want at least that much room 
to facilitate mounting/unmounting gear.

For relay racks, 3 feet front and back is probably the bare minimum you'd 
want.

Side clearance would be determined by things like room size, rack 
placement, airflow (front-to-back vs side-to-side), and any 
legal/regulatory requirements (building/fire codes, ADA compliance, etc).
