its the CM690 standard or CM690 II??.. both have few diferences.. but in general both can fit the h100/h100i on top and bot of the case, in the "690 standard" depending on the motherboard maybe can show some problems..
and the H110i fit in the CM690 II. a friend have the CM 690 II NVIDIA edition + h110 mounted with no problems.. i don't know about the 'standard 690".
I don't see why you couldn't fit a 240 the top of the standard 690 or 690-II. Not enough space on the bottom for a 240 unless you cut out the HDD cages on standard 690. 690-II has the removable cages to put in a 240 or 280 (though the 280 is a stupidly tight fit, take it from experience).
I own both, by far my favorite sub-really expensive cases.
