I wanted to build my first gaming machine. I was looking at a slight CPU cooler upgrade but came across what I thought was a good price for a liquid cooler so I went for it. I also decided to down size the PSU and upgrade my single GPU.
I was looking for a reasonable case and did not really check available space for the radiator or I might have bought something else. With the radiator inside, the USB 3.0 header was partly blocked and it looked like the output area of the motherboard would be choked for air. Since I had the parts I decided to make them work and mounted the radiator outside the case. I made new rear fan holes , allowing it to be mounted 19mm higher up. I slit the existing air holes to create a flap to pass the water block into the case from the rear. After I added a 4 pin case fan (Liquid cooler came with one) for quite browsing.
I am happy with the results. I am still wondering about my SSD & HDD choice though. I may add a SSD later. If I waited about a week I could save saved $20 on the case, $10 on the PSU and another $10 on the Mobo but I did not know it at the time.
I will probably need to build another gaming computer soon as this puts the Dell Laptop my son uses to shame.
