I'm not sure what you mean. What's a mod?
....doomsday prep? lol
Unfortunately, with the cable orientation, I couldn't place the heat sink the way I wanted. However, I haven't done research into whether I can flip the fans over yet.
I believe this case already came with a filter for the bottom :)
I wish I could do 64 GB, but unfortunately my CPU cooler limits me to 4 out of my 8 RAM slots. That may have to change in the future...hehe
With the back fan pulling air away from the heat sink, I figured the GPU would be fine, especially since I have yet to even contemplate overclocking this build. From what I understand, the DarkRock also does one hell of a job dispersing any heat, and my fans haven't yet to speed up based on CPU heat.
They're dice lol. Affixed them to the top with sticky Velcro. The front and bottom fans are the fans pulling air in while the back and top fans push out, so I'm not sure I need the filter for the top. My reasoning is that with the dust guard on top, and fans blowing out, I should be fine. Right?
