Definitely 2 filters. It'd be nice if you can drill the tank and have bulkheads on the bottom. That way there would be even less equipment in the tank.
To me personally Eheims are just a fancy piece of equipment. There is no issue of noise with say a Fluval 404.
The internal Eheim heater is another thing that I consider so-so - yes the heating element is in the filter but there is a probe that you must have inside the tank, meaning a nice big suction cup and a thin black wire...
Lastly - Eheim or not the flow at the outlfow will not be what the filter box says. With a 180 gal tank the hydrostatic head is considerable. My 315 gph Eheims produce a mere 110-120 gph at the outflow (which is 4 ft above the filter).
I'd say consider a cheaper alternative to Eheim. Or.. get 2 big Eheims and enjoy the classy set up!
