This was my first build. I wanted a mini ITX because I wanted it on my desk. This case was great for watercooling. I fit a 280mm rad in this ITX case. The sliding rail was extremely helpful for installing the rad. The GTX 980 works fantastic and runs cool. I get about 40C at idle and around 70C at load. Cable management was pretty good. Being my first time I kinda rushed things with the cabling. All in all this was a great first time build and I learned a lot.
Update: I tore it apart and redid the cable management. Also I turned the radiator around so the tubes weren't bent so much. I was unable to do so the first time because the tubes weren't long enough to mount the radiator on the sled. So I ended up removing the top and mounting it to the already installed sled. Fans are intake along with the front. I wanted as much intake as possible to keep things cool.
