If the graphics card needs to be installed vertically, additional extension cables are required.The installation position of water cooling can be disassembled with a handle, and the position can be adjusted according to your design. If the graphics card is too long, you can adjust the water cooling to the top or other position. This design can be very flexible.
If the CPU is air-cooled, you cannot choose ITX and MATX,because their frames are too short, and the air-cooled CPU will block the graphics card
