I guess I should've caught this right from the start, but I think it's pretty strange that the case has room for three 140mm fans on front/right, yet the lowest fan is totally blocked due to the logo area on the cover. Since this is supposed to be a watercool-based case, with the room for a rad in front, why would they ever design the front cover to totally block the lower fan?? My temps dropped quite a bit while stress testing when I took the cover off, allowing full airflow to the bottom fan, so it just baffles me with this design decision. I have a 420x60 inside the case, fans on the outside, this was the only way to allow room for the res and pump.  Getting a second rad for the top. This will help with my plans, but it still lowers my front rad's ability to dissipate the heat by one fan. 
 
What are the chances getting EVGA to make a revision to this front/right cover, where the whole thing is vented? Or at least an option to order a replacement cover if I decide to dremel that area open?

    A photo would help better understand what it is you are saying.
    Showing how it is blocked from both sides of the fan and the air flow from the fan.

    The last image showing the dust line of the lower third fan shows it pretty well. Did they really need to take up that much space for a logo? Besides that, just put the logo over the vented area!

    You are correct about that "dust line"
    From what I can see from your Far Right Photo with the Dust on the Bottom it still looks like the fan is Pulling In Air.
    What does the Bottom Inside the Case Look Like?
    If you think that is blocking Air Flow take a look at the Corsair 850D and even the 900D both the front is covered with only an 1/4 inch MAX gap all the way around the front cover and that is it.
    From what I can see it is fine and would not call it a design flaw.

    I would be inclined to agree with you if the front fans were for only bringing in air for the case, however these are cooling a radiator, which is more-or-less the intention of that space. That said, having optimal airflow to radiators is necessary, this does not allow that. The lower fan is getting much less airflow than the other two. I see no reason why they had to take up that much space for a logo that takes very little of said space. 
     
    It's making that lower fan pointless on a radiator that needs the airflow. Just because it's getting airflow doesn't mean it's getting the optimal airflow. There's no way it's getting the equal amount of air that the top two are getting, why offer the space for the fan if it gets poor airflow? That would make it pointless to put a radiator that size in that location, hence design flaw. If they wanted it to be just for case air, then there shouldn't be a place for a radiator there. I have a 420 rad that's getting enough airflow for a 280.
     
    I understand where you're coming from, but I still think it's a flaw, considering what this case is intended for. Don't take me the wrong way.

    This was my biggest complaint too. I was thinking of moving the fan so that rather than be against the plastic/logo, have it on the INSIDE closer to the HDD tray. Basically, just move it on the other side of the mounting area.
     
    I've heard other people counter this argument and say that the radiator should be against the filter and the fans should be pushing OUT from the inside.

    I noticed this right away as well when I got my DG-87.  I too wish they would not have done that just to put their logo on the front.  Would be nice of them to make a new front cover to fix it.

    Can the case be easily modded to move the front radiator higher up ?
     
    I think the lower section should be a metal mesh to promote better airflow, instead of the current solid material - logo could then stay

    ya... that is why i do this and it helps temps by 3C in my dual 420mm rad system
     

     
    i click in the top two and use that sharpie to allow the lowest fan a little breathing room. most air still goes through the dust filter this way too, unless its clogged.

    You should install one more wall of filters. 
    Example demciflex. One dust filter is not enough. 
    I reduce dust in case for 70-80% installing Demciflex under CORSAIR filter on 650D.

    That is strange how they put spots for 3 fans, but fail to design the front of the case to allow enough air flow.

    Yeah, its pretty frustrating.. A case optimized for watercooling and giant radiators and you can't even fully cool one properly. Currently deciding whether or not it's dremel time.

    Well, maybe we can petition EVGA to redesign the front grill, and give us the ability to replace it for say 5$.
    I know for a fact that the material used to make the grill would be far short of 5$, they can even leave the EVGA logo out of the mold to save money, as the side is supposed to be the front anyway.
     
    I would pay the 5 bucks for it.  
    While they are at it, a better fltfer for the top would be nice.

    I'd pay $5 for a fix.

    3rd for paying for fixed replacement.
     
    that being said one could very simply flip the design upside down as there is already a dead zone above the top fan for the top radiator. this dead zone could be where you place the EVGA logo, as long as it still looks good, just my 2 cents on the matter.

    They paid for a mold to me made for the grill, they can pay a little more and have it modified, and Bingo... a new grill with slots the full height of the part.
    Very little money needed to modify, would pay for itself with the 5$ everyone would pay for a better grill.
     
    Looking at it now, so exposed... i really dont see how EVGA would have approved of this design, knowing it is to be the ultimate case for liquid and air cooling.
    I know i would not have let it go.

    well the thing is that these kind of things are part of the learning curve and being EVGA's second attempt i find that they did most things right and only missed a few small things. like this air intake, the high HDD temps behind the mobo due to poor/no airflow, poor airflow design with dual radiators (3 in and 5 out doesn't give positive pressure), and the non PWN fan controller. those are the only four things i personally do not like about this case design.

    well the 360mm rad can slide up some and not be as blocked. but with the 420mm rad that cover nearly blocks that 3rd fan completely.

    Will do the same for feedback. Was wondering why my front fans seemed to not push a lot of air. Removed front grill, my temps are now stable and a ton more air is being pushed by my fans
     

    As long as your popular enough, you can get away with anything.

    because of this i also reversed the left two fans to push in, so i have 5 in and 3 out.

    I did not notice this when I did my build, I would also buy the new grill if they ever make one :)

    if you are only using one rad that is 3 fans long i would put it on top. if it is only a 2 fan rad you can still put it in front just make sure its on the top fan slots instead of the bottom ones.

    I just un-pluged the bottom (spare) fan and used the top for the EVGA 2 fan radiator.
    The case had one fan there already on the lef-top - I did move them a bit to leave no gaps.
    A week later I move the 2 back mounted 3.5 inch HDD to the  right disk rack by that fan and re-plugged in to just cool the disk drives.
