Video Card clearance:

• There is 500mm of clearance before the reaching the front of the case if the HDD cage is removed. Suggested/Supported video card lenght 370mm.

CPU Tower coolers:

• CPU heat-sink height clearance is about 170mm.(from motherboard to the glass)
• Large CPU backplate cutout.

Assembly of the components in to this case was pretty easy as the Carbide 678C has plenty of space to work around the tight spots. The area of concern in my build was the power supply. I am using a Cooler Master 1200 Gold power supply and it just barely fits into the power supply space but without any clearance space on the top. Fan set up and Radiator set up was a breeze as well. The entire fan system was attached to the PWM repeater and connected to the PWM controller on the motherboard. No issues with rear cabling but I wish there was more room on the back between the internal frame and the door.
