I've installed some filters in the haf x since dust is a bit of a problem where I live at the moment and open case just doesn't seem reasonable due to space restrictions. Can't really put it on the floor.

I get your logic though. What I meant about the holes is that I can see the gpu through the top fans from where I sit. I block it and get reduced noise, probably also due to damping/removing vibration on the case from the pressure. I've tried a few different combinations for positioning the cpu fan, but without significant performance changes. Not much else to do with the Haf x, except to change the fans and do some modding to the case.

Thanks for the viewpoint though. Bit hard core for me to get huge noctuas. As you said, traditional cases make it tricky. Will look into it though. Aftermarket cooling/fans seem to be the way to go though.

Another option is the Cooltek/Jonsbo W2, which is a side-by-side style. More HDD space than the Silverstone, and likely better made, but you'd have to import it because there's no Rosewill version as of yet.

Yeah, some of my friends seem to like the idea that relatively simple works best. One big fan gushing against the gpu on the haf x is just one thing.. I could use the plastic part that directed the airflow against the gpu with dual HD6850's, but no space with the gtx780, ha.

But yeah, those are some good suggestions for cases. Seem minimalistic and decent in design. I like the Haf X for space and I used to have a crossfire configuration there. Have thought about getting another used 780 for SLI at some point, but I've found I don't play that much or seriously anymore, so maybe the Haf X is a bit too big. Borderlands pre sequel (not very good  ) ran with everything maxed (only FHD) smoothly at constant 60fps, and so do most the other games I play as well.

Good point about the seriousness. I mean I don't have a reference. I do not mean to go over the top, but so that I can enjoy music on open headphones. Interesting to view so opposing opinions. I know I can get good quality aftermarket fans and coolers, so maybe get those and a new case with decent (not superb) airflow, but also better noise dampening. I don't think these two approaches are mutually exclusive completely?

The filters were a conscious sacrifice to airflow, but that was when I was rocking a set of Paradox for computer stuff. I haven't done anything yet to the setup.

I live underground next to a dirt road so yeah, dust is a problem. Sure, I clean the computer every now and then and keep the place relatively clean, but am too lazy to get the computer out and open it up for thorough cleaning too often. I have a tight corner for work space, so at the moment I am not able to move the computer off the floor. I have some stuff under the wheels of the Haf X though so it doesn't look like santa claus always.

I'd like a supercar with over 1000hp, do 0-120mph in under 5 secs, have 50mpg, go off road, uses cheap tires, ride like a Phantom, and cost under 50k.

You got too many restrictions. Be willing to compromise somewhere. You can't have quiet with filters. A smaller case will be a lot easier to carry outside to clean. Dampening won't be needed if you overkill on coolers. That i7 950 isn't helping your goal either so you better overkill or upgrade.
