First of all, the CoolerMaster Stacker was completely ripped apart, and after some blood, sweat and tears, there was a pile of bits that were no longer needed.
The left over parts from the inside of the case were then primed and given a first coat of blue paint. The pair didn't use expensive airbrushing tools; instead, they used a trusty can of spray paint bought from a local store. One thing to note here, don't try spray painting without a mask at home! To their credit, they were spray painting in a garage with the door open, so at the least, the area was well ventilated.
A few coats of blue paint later and we had a very blue CM Stacker, albeit in bits. Vemis was used to finish off the parts of the case with a shiny top coat.
Once the paint was dry, they started putting the case back together again. Some green CoolerMaster LED fans were installed to check out the blue / green colour combination that was going to be used throughout the case. They were happy with how this looked, although it does look a bit strange at this early stage.
During this process, the first of their components were installed in readiness for planning how they'd get their watercooling kit integrated into the case. Here you can see the OCZ ModStream power supply and Ehiem 1250 pump being test fitted at the bottom of the case. Normally, the power supply is installed at the top of a CM Stacker, so they're going to re-build the rear of the chassis.
