The first Koolinator had grown over time, it become more and more cluttered. In addition it was very heavy and the design kinda outdated. After I finished the Plexi mod for my 'server', I decided in 2006 to built a new Koolinator based on a high end Lian Li case. I used this case till I decided in 2012 to go smaller.
List of modifications:
The four transparent fans were provided with custom made RGB LED strips since you couldn't buy them back then. The result was quite colourful.
I embedded the Diablo logo in the Plexiglas for the drive cage window. I used the LED colours; white, red and orange. The white spots to the right and left were reflections.
The other side window had the Diablo 3 angel image. I used two colours for this image, blue and yellow.
Internally the case was quite the mess. This is the result of two separated watercooling systems (1 for CPU, 1 for GPU) and 2 power supplies.
Later I replaced the VGA cards by a Xfire setup wichout watercooling. This mode the case internals look much cleaner.
This image shows the secondary windows display at the top and the blue (inactive) display for automation of the cooling. That part I never finished.
