I have the same case with water cooling. Here is the Water cooling kit
I'm using. My CPU is Athlon TB 1200. The temps are case 28C, CPU Idle 32C, ambient 25C.
Here are some pictures. They are not so good, but more than nothing:
I cutted 120mm hole for the radiator.
The radiator is mounted with four screws to the side panel.
Another view. Ugly but works very well.
I cutted the motherboard tray for the radiator and the fans.
That’s the pump and the radiator with the fans behind the HDD removable bay.
The two 80mm fans sucks cold air through the radiator from outside of the case.
I hope this help.
