After some rest the project is started up again. This time I've decided to go water cooling. Even though I have not ordered the parts yet I have started with the modifications to the Coolermaster CM690 case.
I decided I'm going to top mount the rad on the inside of the case and have the fans on the top pulling the air through the rad.
Since there it is not possible to mount the fan under the mesh top of the CM690 I decided to remove the mesh (which cut my finger) and cut out the honeycomb design. You can see my idea from the pictures below.
The fans are not mounted they are just sitting in there showing my idea.
