i can honestly say that throwing modular leds into my cube was one of the best upgrades ive done. 2:1 rb:nw is the way to go hands down IMO. im running 26 leds at 65, and 75% and my sps still thinks its a little much. the heatsink and all that fits into the hood just fine if you shave off some of the heatsink. i hit 82 once this summer but i think it was cause i have i skimmer feed pump, one skimmer pump a return pump and a circulation pump all running in my sump. i should probably plumb my skimmer into the overflow one of these days
oh and if you do buy from martin make sure you get the antec true silent fan, the only way to hear it is by touching my ear to my hood, super silent.
