And don't forget the floor load.  Our EMC Clariions are heavy enough that I can't use a tile under them with any holes of any kind in them (especially vents) or I have tile surface deflection that's out of spec.  And our floor in the main data center is rated 1,500 lbs (avoirdupois) per square foot.  And the subfloor loading has to be considered, as well as how much the underfloor will 'flow' in CFM......
