I'm trying to find a measurement of the Xigmatek HDT-S1283 from the mobo to the highest point on the heatsink. I'm guessing its close to 7" but I would like to verify. If any one can take a measurement or already knows this, that would be great. I have exactly 6 1/4" to play with in my case and not sure if the Xigmatek HDT-S1283 will fit.
