Quote:10cm?? Thing would look like a giraffe!
I base the 40-50mm clearance on area of 2x 140mm circles (PSU & case fans) 307.7sq cm compared to area of circumference of one circle plus 280mm (2x the distance between fans) times the clearance (40-50mm) being near equal area 287.8-359.8sq cm. I know, the actual area of airflow through fan needs the area of fan hub subtracted but the resistance in airflow turning 90* to enter fan makes up for it.
My avatar is good example of 55mm clearance. 50mm casters plus 5mm in frame.
