Make sure to pay attention to the type of fans, though, I'm pretty sure you can only fit three fans in front (with HDD cage removed) if they're all 120mm fans.
I was getting around to mentioning that to you, glad you found it. I was busy adding some pictures and updating my build page, please check out the pictures if it wasn't clear what I was saying earlier.
As for the heat getting trapped below the GPU, I don't know that I can really give input on that without seeing what the inside of your case looks like. it could be that your exhaust fans aren't working hard enough to pull air up and out, or that your GPU fans themselves have nowhere to dump the hot air. And that's only if you have no issues with the front intake fans now or later on.
Since each case isn't really more than a rectangular box with holes in the front and back (and sometimes top and bottom), improving airflow really comes down to where and how you can place the fans and (in your case, not mine) radiators. Getting a larger tower may not really help at all, if you don't have enough fans to move air where it needs to go. That's my take on that.
When a tower has issues with airflow, it usually comes down to too-small gaps in the front that choke off the intake fans. Exhaust capacity is almost never an issue. If you look for a new case, make sure that the intake isn't choked off like it is with this case by default.
EDIT: Apparently amazon does offer several options you can just purchase and slap into your case that will do well. https://amzn.to/2DNomsp
Sorry, I never did find a large magnetic dust filter, I jury-rigged an alternative solution that I'm mostly happy with. Here's what I ended up doing:
Removed the two small dust filters from the top and bottom of the front cover and packed them away. They're restricting an already restricted airflow.
Took the two square dust filters meant for the top exhaust and placed them directly over the front intake fans. This way air can freely enter the chamber behind the front cover and the intake fans are still filtered.
*This leaves a lot of little holes to the sides of the intake fans and also to the chamber beneath the power supply shroud. You could use electrical tape or duct tape to cover these holes, it doesn't need to be pretty if you intend to keep the front cover of the case on. I did nothing to cover these holes up so there is some dust buildup there, but I rely on positive pressure to keep that to a minimum. I can go several weeks with minimal dust buildup.
I'm not near home now, but I can add pictures of what I've done if that helps you.
You could also DIY your own magnetic dust filter using some magnetic tape from your local hobby store and a sheet of plastic mesh you can get off amazon OR you could cannibalize a kitchen strainer/sifter.
Hope this helps!
Two 140mm fans in the front, one 120mm fan in the back. I have one 120mm fan in the top rear slot for exhaust. Can also just check the pictures I took of the build.
I dont have the best eye for colors, but mine don't appear slightly yellow to me. They do appear a slightly different shade of white though, since they're made of plastic while the surrounding case is painted metal.
I keep it at 2933MHz, as that seems to eliminate random crashes I would get while playing games. To me, that's an acceptable overclock. The only reason I chose the 3200MHz kit was an ongoing sale, and it had LED effects over my first choice.
Mostly it was a result of extra problems getting the build off the ground, especially with the X version I got without a stock cooler, but now that I've gotten it out of the way and overclocked it a touch, it's no longer an issue.
After looking at your build, that's quite a compliment! Yours looks amazing compared to mine.
Thanks! That was my thought going in, I figured people would be more interested in the build side of things for this review, especially considering my troubles getting this system off the ground. But yes, I definitely agree that performance shouldn't be an issue, especially going forward. I do think going with the 1600 would have saved me some build troubles though. Oh well, live and learn.
Nice look, love the blue aesthetic. Have you played around with overclocking the RAM? I've been hearing 2933Mhz.
