I have a 15x15x15 Cube designed by Custom King w/ a less than 2 week old 75 watt HQI Clamp on, the tank itself has a built in OFB, and 1" BH for drain, nano stand, 10 gallon fuge/sump drilled as well. I just paid $150 2 weeks ago for the Viper MH's, but I am willing to take $160 for the whole set up!
