I will use a little unconventional mounting option for my HardWareLabs Black Ice Nemesis GTS420 Xflow radiator and be quiet Silent Wings 3 fans. The HWL radiator will be mounted outside the be quiet! Dark Base Pro 900 between the case cover and frame. This option lets me expose the fans inside the case and give maximum amount of clearance to keep the motherboard and EKWB monoblock as the heros. 

I measure with a Corsair ML140 fan, but will use the amazingly good looking and awesome fans from be quiet! – be quiet! Silent Wings 3 in this project.

I did a quick test mount with one fan to take measurements of heights and positions. My cardboard motherboard dummy isn’t making my case justice 😀

With HardWareLabs 420 x-flow radiator, the inlet and outlet of the radiator will not work with the case. Used my mounting fan to take measurements.

Important not to keep the mounting rails inside the case. I never know what the future will require, but need the radiator centered in the case. Will use the upper part and make a continuous turn for a hole big enough for my Alphacool water cooling fittings.  Nothing I can’t handle with a drill and a hand file. Just not need to ensure I cut in the right place.

Centered and alined. I need to fit all three be quiet! Slient Wings 3 fans after my mod. Time to cut.

This looks just right. The inlet / outlet of my HardWareLabs 420 x-flow radiator will now let me mount it on the outside of the case frame. One side done, time to fix next.

Managed to keep the entire mounting area intact and still make the inlet / outlet hole in the case large enough.

Seems like this casemod will work. I covered the HWL radiator in plastic to keep it from scratching while modding. It will be removed for the finished product, I promise 🙂

One final thing to test. Secure that the water cooling fittings fit when the fans are mounted? They fit, casemod done. As a result of this casemod I will create a case fan shroud to cover the side of the fans for a cleaner look, maybe do that in carbon fiber…

    I’m very interested in how this project is proceeding because I’m working on a similar build myself, and could use some advice from someone more experienced with the DBP900. If you’re interested in talking with me about it, please reach out. Have a few questions about your radiator fitment and what caveats came along with it.
