The MaxOrb is designed to fit all socket 775, AM2, 939, 940 and 754 motherboards. Even though the cooler is large, a majority of the mass is located several inches above the motherboard and components. When using the MaxOrb with extremely large memory modules such as Corsair's Dominator Series you may have to move the memory over one slot. I tested the MaxOrb on an XFX reference 680i SLI with a 2GB kit from Winchip and needed to move the memory module closest to the CPU over one slot. When doing this remember to move the second module over one slot to retain dual channel capability.
The Thermaltake MaxOrb uses a 3-pin power connector on the fan with a rheostat placed on the cooler. With the fan speed adjustment located on the unit, the option of controlling the speed from the back of the case is eliminated, but so is the wiring mess associated with it. A set it and forget it mentality has to be used but to be honest I can't say I like stringing extra cabling all over my case anyhow.
