of the two the first one is betterbecause of the nice gig fan on the side and a space for a 120mm in the front,but again it only has space for 800mm at the back which is not ideal for good airflow
If you get that case you dont need the 2 80mm fans mate,just get a 120mm for the back and your good to go,you can get a 120mm for the same price as 2 80mm
Defo keep intel, everyone is jumping off the sinking ship that is amd........
Stick with the p31 gigabyte mobo or even buy a asus P5B if you want to overclock, those mobos are still turning out some awesome overclocks. They dont look like much but wont let you down
