This is my first Pc build and mod. I add a PSU cover, designed and 3D printed fan shrouds to compliment the GPU. I modded the top of the case so the 3 fans would be centered and raised up about 5/8". I add one extra fan to the top. Than I, made a custom top grill by using two front covers. I painted all the dust filters red. I used the top panel of the Corsair 740 Air as a drive cage cover. That's my favorite part. The finished product is pretty nice.
