hi, i am wondering if anyone could give me some information on changing my z77 mobo to the x99 mobo, i know i need a cpu compatible with the x99 and ddr4 memory, but my main concern is, i know they are both atx form factor, but i noticed the z77 is ( 30.5 cm x 21.8 cm ) and the x99 is (30.5cm x 24.4cm) i have a Aerocool GT-S Black Full Tower Gaming Case, and i noticed that the internal connectors or headers are slightly different on both mobo's and i was wondering if i disconnect the 24 pin and 8 pin and the usb 3 connector out of the p8z77, would i only have to connect those connectors back in the x99 when it is installed, or will i have to add more connectors, i know how to remove the cpu, liquid cooler, and replace it all, i am still learning, but i would want to save a few pound in doing it myself than getting it done by a repair shop, any information would be helpful thankyou
