nah... the proint is that we're calcuting our existing systems
at 10ton AC... but the "server room experts" ( aka real estate 
agents and or interior designers ) wnat to use 500BTU/hr 
as if it was s regular cubicle 

- also, the current 4-ton AC that they have allows the server room 
  temp to go over 80F ... at nights ... instead maintaining
  at 65F

	- and i keep telling them it's not a 4-ton ac ..
	and at least the real estate agents laughed too
	when they say the AC unit

	- the AC has official looking part# and manufacturer
	but if you google for it, it'd show a non-existing
	model#  and if you look closely at the AC, it is 
	a home-brew AC built with spare parts ( imho )

- the entertaining part ...
	- their "server room experts" are clueless interior
	decorators per the google results of their names
