My Enlight would probably fit a DD cube with a 92 mm fan. MAYBE a 120, but cutting the hole for the 92mm was difficult enough. I haven't done it yet myself because I don't want to buy any pre-made parts for my water cooler. I have been working on it for a while now and the fun of it for me is doing it all myself. I don't even care about how high I can overclock even though i know my duron would do 1100 with a voltage mod. It does 1030 or so with 1.89.
