riba, Sonnet 1.2GHz for Cube has got a specific heatsink for this model. I think the one for the towers is different and You'd have to modify it (or the Cube) in order to fit. It will of course, void your warranty. There arealready discussions about this on cubeowner.com. Check it by yourself at the CPU subforums menu. Cheers, LM >>>riba at ml1.net 03/15/06 11:04 am >>> I decided to go ahead and finally buy a CPU upgrade. I want to get the Sonnet 1.2 GHz upgrade but it seems they are hard to find with a decent price. Provantage has the 'non-cube' version available for $211: http://www.provantage.com/sonnet-sg4-1200-2m~7SONT02T.htm Am I right that the only difference between cube version and this one is the inclusion of the cube kit? What does this cube kit contain? I know there was a fan included, but I already have fan inside. Was there a special heatsink adapter? Thanks!
