What's the quietist high end computer case I can get? I'm gona throw in a gtx980 and an i7

Fractal Design R4 won the quiet gaming case round-up on here overall. if you want the most silent, regardless of thermal efficiency and price, a Nanoxia Deep Silence series case may be what you're looking for as they even add silencing pads to the interior of the case. if you're keen to DIY you might be better suited to getting something like a Fractal Design or an NXZT H440 (NO EXTERNAL DRIVE OPENINGS) and a roll of Dynamat to line the interior panels.
 


Will the fractal design r4 let in enough air to cool a gtx980 and an i7?
If its so good why is it cheaper than other cases?
 
Prices vary by a lot of things, like alienware pcs, they suck, but cost a lot more.

Or how some 20 dollar wines are better than 100 dollar wines.

Of course you usually pay for what you get.

As long as it has what you need the price shouldn't matter if it is less than others.

And when it comes to computers buy from reputable brands.

And NEVER, absolutely NEVER, buy a case for it's looks.
 
Fractal Design makes excellent cases overall. I went with them for my recent build, and aside from the front accessories port cable being a little short, I felt like I recieved excellent value for what i spent. it should have more than enough airflow for your needs; however keep in mind that the more vents a case has, the better airflow/cooling it will have, however it will let more noise through. the Deep Silence case is more expensive because it has that acoustic foam lining the insides to make it more quiet. a Modern i7 and a 980 should have no sweat operating in a marginally unvented case. the Maxwell architecture from nVidia is very efficient for it's power, same with modern Devil's Canyon or skylake chip. secondary noise generating areas to pay attention to is storage; most mechanical drives generate more sound than the sum of the rest of the PC's fans put together, including the quiet ones. also, a 80+ gold PSU with PFC and fanless operation rated for high temps (EVGA Supernova G2?) will operate with less heat generation, often running completely fanless, and due to high temp tolerance will not be affected if there's a ventilation issue in the case. get a big, meaty Cryorig or Noctura with nice, quiet 140+mm fans or even some liquid cooling solutions can help assist in making the machine nearly totally silent.
 
Get the Fractal R5, an upgrade to the R4.
I just got mine today. Waiting for other parts to start installing.

 
Regardless of case you'll be able to lessen noise by dropping an AIO cooler on the CPU and replacing the stock fans with a fan that has a high static pressure rating - I prefer Cougars. And while some of the cases that are mentioned above will dampen sounds, running any GPU on air while it's at load - even a GTX 980 will make noticeable noise. I think it becomes about personal preference and tolerance. I run everything on a liquid loop but can still hear my fans even though they are super quiet - others sit by my rig and can't hear a thing because their hearing isn't as sensitive.

There's also all sort of aftermarket foams that you can add to most any case to help dampen the sound.
 


what's the difference between supernova and other evga power supplies?
 
Supernova's are reliable, and sturdy, though there could be a bit of coil whine, which is a tiny noise made by power coils, it's annoying, but, hey, that's what headphones are for.

Note all PSUs have that problem sometimes, but other than that supernova is pretty great. It'll power your setup in a jiffy!
 
the Supernova; specifically the G2 series of PSUs are made by Superflower. multiple, different tests/reviews of these units show their efficiency is not only great, but in some units almost at platinum levels, and only gets better when they're hotboxed. usually their ratings are set for 50C (most other PSUs are rated for 40C, sometimes lower) as well as they have among the best ripple suppression and regulation of any PSU tested. If you want the best, PSU OEMs Superflower, Seasonic, and Delta are the ones you want. there's a bunch of Tier2 OEMs that do very well, but when you can get a Tier1 option (in most cases) for under $100, there's really no reason not to. iirc EVGA has a GS-model line unit that's made by Seasonic for under $70 as well as Seasonic themselves.
