before putting the mobo in to the case, place it on to the cardboard box it came whit, place 1 stick of ram in to the closest slot to the CPU, and place the cooler on the slot where the CPU is going to be ( just for testing ( dont take off the plastic cover for the termal pad on the cooler ) ).
best thing is to try and boot up the pc on the outside before putting it into the case..
just PSU,CPU, ram and HDMI to the onboard of the motherboard. ( use stock cooler for this if there is one in the case of the CPU ).
if that works then place it in to the case.
and attach every thing ( let only the disk/disk's you are going to instal OS on plugged in and the dvd/bd rom ) and instal OS on it.
after that is done plugg inn the other disk's
try and instal as minimum of programs on the ssd ass possible.
place games and large programs on the HDD's
plugg inn as mutch as you can of power to the motherboard. 24pin, 8pin ( abow the CPU ), 4pin ( abow the CPU ), 4pin molex ( addittional power to video cards ).
if cables dont reach on the back of the motherboard just take it in front and get extenders laters to clean it up 🙂
