Thermaltake DuOrb CPU cooler + Antec 300

I just upgraded my CPU from an AMD Phenom II X2 550 to an Phenom II X4 940, and the temperatures aren't to my liking, plus, the DuOrb just looks awesome. But I want to make sure it will fit in my case. I've had an Antec 300 since i first built this computer now. I just got my corsair 650TX, so my wires are organized, and with my 2 4850's it'll look pretty awesome with that CPU cooler, considering the window I put in the case. So has anyone done this? Will it fit?
