I need a mini itx mobo with 4 or more Pwm fan headers! fan headers and I can't find one!!
Unlikely that you will. For that many and PWM you should look into a fan controller. There is almost no chance that exists for mitx.
Do you know of any cheap fan controllers?
Do you need for 4 pin support or do you want PWM output?
If you just need to support 4 PWM fan both the Z87-I Deluxe and Maximus VI Impact offer 4 fan headers ( all 4 pin ) with control for each of header. No need to by a fan controller the FanXpert II functionality is very advanced.
This is one of the key differences on ASUS boards is the advanced fan control functionality implemented on the boards.
Hope this helps!
Best of luck with the build.
