These two drawings show this project in the earliest stages of design. Although many details have changed since then, the original layout remains unchanged.
Using this arrangement, three separate cooling zones are created, each unaffected by the others. The mainboard resides in its own area and is not affected by heat from other components. The hard drives and optical drives are also isolated, sharing space in their cooling zone with the water pump and power supply. Air from both of these zones is evacuated out of the top of the case through three 80mm exhaust fans. In the picture on the right, you can see how allowing the LianLi side of the case to extend beyond the greenhouse, creates the third zone, giving a clear flow of air to cool the radiator from outside and exhausting it straight through and out of the case, just below the power supply.
A Quick Look Around
Don’t be fooled by pictures that make this rig look large, because BaDassII is smaller than you may think. She measures 16 Â½’ tall x 17′ wide x 19′ deep. Here she sits at work, opposite her predecessor, the original BaDass, a liquid cooled dual AMD 2400 MP rig.
The plexiglass cover of the greenhouse swings out with a quick release of the handles at the upper edge, making access to the inside quite easy. After it’s opened, it lifts right out of the slot. The front window also pops out, so that add-on cards can be removed without taking anything apart. It turns out that the easiest way to remove the Wildcat4 graphics card, is right through the front window.
At the front left corner is a modified Zalman fan controller. It may seem odd at first to have controls on the side of the case, but the way BaDassII sits on the desk, it works well. A pair of USB ports, cathode lights switches, three HDD activity lights, and an 80mm fan grille are at the front of the greenhouse.
It seemed at first that the jog in the back of the case, while allowing the radiator’s airflow to work well, might be otherwise awkward. In practice, it works fine, helping to organize the jumble of cables hooking into this rig and making a convenient place for the air trap.
Here’s a little eye candy, pictures taken with the greenhouse covers off. First, a look at the two Xeons cooled with DangerDen RBX blocks. The green covers actually tone down the pair of green cathode lights inside.
This is a look at the manifold receiving the returning coolant, below the CPU blocks. The coolant lines behind them are coming directly from the radiator, after passing under the mainboard. To the right is the return line to the pump and to the left is the line to the air trap.
In the back of the greenhouse is the external air trap, where coolant gets topped off. This little unit was put together with some special attention from Scott over at HighSpeedPC. The line to it runs through a rear window.
On the ‘far side’, there isn’t much to see, but it’s where the radiator inlet is. To seal the incoming air, two layers of high density foam surround the radiator.
