With 90% steel construction, we're able to deliver superior durability and create a case you can keep build to build.
A sea of space fills the interior, with a grommet-less steel cable management bar splitting the front intake from the rest of the case while keeping your cables tame and hidden.
Comes complete with the basics, USB 3.0 and HD Audio, but gives you even more with high quality materials, a smart interior layout, and tons of cable management potential.
We care about the little things. Steel plated audio jacks, captive thumb screws, and over twenty cable management points are just a few of the small touches that we've added.
Measuring in at 445mm high and 432mm long, the S340 bucks the trend of tall, thick cases, enabling you to keep your PC's footprint to a minimum.
Performance is not sacrificed for size with this small mid tower boasting full compatibility with our Kraken X61 and X31 liquid coolers.
The removal of the front 5.25" bays allows us to bring an unprecedented level of neatness to the interior of your case and showcase your build with an enormous side window. Our GRID+ (sold separately) ensures that fan control is not missed despite the removal of the front drive bays.

Great Value

Pros: - Affordable
- Case fans actually very good

Cons: - Not roomy enough for BIG GPU (Not a real con since I doubt most mid tower case fit BIG GPU)
- Not really thumb screws
- Removing the front to put in front case fans was a little difficult.
- Glass does scratch easily

Overall Review: For the price, this is a great buy. Easy to build in, many people with the same case to help in case you don't know how to do something. It looks very good too.

Sleek Case.

Pros: - Great price
- Sleek/sexy
- Enough room for almost anything you could want to upgrade(Huge GPUs, Oversized CPU coolers, etc)
- Case fans are quiet
- Solid cable management

Cons: - Scratches really easily
- No bay for optical drive - but in 2018 and onward these are becoming more and more obsolete so it doesn't matter as much
- Gets dirty and shows fingerprints frequently because of finish

Overall Review: Great tower overall. Own two of these and they both feel like they'll last a while.

Hardcore Drill Action

Pros: Good Case, Cables organized inside. Nice Sleek Finish. Easily removed, and replaced sides (two thumbscrews each). Would get five stars but some of the thumbscrews were like twisted diagonally. You can tell they drilled them on hardcore. Had to use a screwdriver to remove/replace a couple of them, but you can switch out for some of the lesser used ones. Once everything's figured out though its a good case. Very purdy :)

Cons: The thumbscrews were slightly jacked up

Good price, clean looking internals

Pros: The case does a great job with wire management and hiding the cable octopus. Most organized case I've ever owned. Front of the case is nice and shiny, minimalist looking design, which is exactly what I wanted. Included 2 fans on the top and rear of the case was nice, I added a 140mm on the front.

Cons: Case appears a little cheap, as I had to press the back panel inward to get video card mounting plate to line up properly (just off by a little bit). Also a little complicated for adding/removing cards, could have been much nicer with a screwless design. Glass window seems to smudge/scratch easily.

Overall Review: I don't mean to deter anyone, for the price, this is a great case. The most frustrating part was the video card mounting, as I really didn't want to 'force' anything when it comes to a video card.

Rebate Blues

Pros: Great case to build in ,luv it ,great modding case .

Cons: none for the case but if you are shopping for something on Newegg and let the so called rebate influence your buying decisions don't , its like a dog and pony show trying to get your rebate money back so avoid all the pain an just buy what you need expecting that and none of the headaches,I wish I had.

Overall Review: I would have bought the same case because NZXT makes a good product I just would have bought it somewhere else.

Good for cable management, difficult threads

Pros: Sleek design, cables are hidden.

Cons: A few mounts for the motherboard were very difficult to catch a thread at the proper angle. I was very careful to not crossthread, but a lot of reversing and trying kept resulting in crossthreading. Might be paint in the threads? Even one of the thumb screws on the back, after removed I couldn't catch a thread. Very strange, I work on cars, mobile device repair etc. It wasn't user error. Otherwise I like the case.

Overall Review: Just be really careful to try to lightly get the screws into the threads before you jam them. If it seems to crossthread, switch to another screw, just in case.
