It just fits on a Gigabyte P35C-DS3R - literally 1 or 2 mm from the top of the case.
If you have one of those - small installation tip, once you've fit the Tuniq, remember to fit the 4 pin CPU power cable before you fit the mobo into the case. The Tuniq totally covers the board connector, and there is no way to get at it once the mobo is in. I learned the hard way...
