Thanks for the info. Really helpful!!!
Sorry to bother but I see there are two types of BTX fans, Type I and II, will either work on the D945Gcz board. Is the Type II better than Type I?
To clarify things
1 In order to use a BTX motherboard you need: a BTX chassis and a BTX Fan.
The BTX standard allows for two case heights - Type I and Type II. Type I cases are 3.98" in height and can use normal expansion cards, while Type II cases are for small form factor designs and are 3.0" in height. Expansion cards would either use risers or be low profile in a Type II case.
Meaning that you need to know what chassis you have in order to get the fan. Type 1 or 2. Unless you have a BTX chassis you won’t be able to FIT the BTX fan, as the chassis has a Plate on the back that supports the FAN in place. And the high of the chassis determine the FAN type.
