The S340 mid tower case combines an uncompromising approach to chassis design and pure, functional style to bring you the new standard in case design. A compact form factor and a unique, build-friendly layout allows this durable mid-tower to be extremely easy to use regardless of experience level. 360 degrees of steel casing and heavy duty side panels makes this one of the most durable cases NZXT has ever made. Features Unique Interior Layout
A sea of space fills the interior, with the grommet-less steel cable management bar splitting the front intake from the rest of the case and keeping cables hidden and tame.

All Steel Construction
With 90% of the case being steel, NZXT are able to deliver superior durability for a case you can keep build to build.

Everything You Need. And Then Some.
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 NZXT have added.

Compact Size
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.

Ease of Use
Tons of open space and functional design makes this one of the easiest cases to build in that NZXT have made to date.

NZXT Source 340 Black with Blue Trim Mid Tower Case with USB3 Side Window 2x120mm Quiet Fans w/o PSU is rated 4.7 out of 5 by 7.
Rated 5 out of 5 by from Amazing case for the money! It's not made clear in the description but this is actually the revised Source 340 with a very sharp matt finish (the older version had a semi-gloss finish which looked kinda cheap). Great value and very sturdy - the only 'cheap' aspect is the plexi panel but it doesn't really bother me since the rest of the case is so nice. Getting the SSDs to fit was a bit fiddly since a standard PSU power cable puts them under a bit of tension if you use the provided cut-outs but other than that, no issues with the build - in fact, the removal of the 5 1/4" bays gives you lots of room to work in a pretty compact mid-tower case. Highly recommended!

Rated 5 out of 5 by from Very clear build with Water cooling Love the mat finish and cable management. I wanted to put a custom water loop in here but there is a maximum 62mm clearance in the front for a radiator - so with 25mm fans you have a max radiator thickness of 35mm ish (you can loosen the cable management bar screws to squeeze it in). Mine worked well with the XSPC 280mm rad. The HD mountings for 3.5" drives are very basic - no cadies. Very pleased.

Rated 5 out of 5 by from Brilliant and cheap excellent case the window does seem mildly flimsy but has stood up well. I actually like the fact that it has no space for a cd drive (honestly when did you last use one) makes the case smaller and easier to sort out wires. It's extremely easy to cable tidy. everything looks amazing inside.

Rated 4 out of 5 by from Great Case Very good case for the value, stylish, nice cable management system, love the lower shroud that covers all the PSU cables. Only issue is a little scratch on one of the sides, the case seems like it would scratch easily if you don't take care of it, I wouldn't be putting phones and cameras on the top of it. Otherwise a great stylish case that would be great for high end gaming rig.

Rated 5 out of 5 by from Feature Packed Case I actually downsized from a full atx predator case to this after my build design changed dramatically. i was a little nervous about the amount of room i would have to build as i "had" a h100 and a gtx 970 to fit in but when it arrived i was amazed at how easy it was to build in. the cable management option are amazing, it fits xl gpu's, fits 240mm aio coolers and hides my hideous non modular psu. the only niggle i have is my sp120 fans make the top of the case vibrate. nothing some rubber washers diddnt fix but took me a few days to get hold of some. all in all fantastic little case and would recommend to anyone who wants a mid tower case that looks great and has all the functionality that you require

Rated 4 out of 5 by from Excellent Case for the Money I wanted a case that didn't have the optical drive bay for a smaller build. I slapped an ATX MoBo in it with a Corsair H75 water cooler but the only issue I had was I was unable to mount the radiator on the top front intake as the metal bar to help with cable management was in the way. Other than this small issue the case is a dream, all my parts fitted even the huge Gigabyte GTX 980 I placed in it. If you're looking for a budget case that looks good and has excellent you can't go wrong with this one.

Questions & Answers

case Finish

I was just wondering after looking at the picture if the whole case has a matte finish as some of the source 340 case are not and have a horrible shiny finish on the side panels and front. Cheers
Asked by: MattNew
Just bought one - this is the matte finished version. Looks Great!

Airflow from front fans.

Hello, What's the airflow like with the door closed like in the picture? it looks like the fans would struggle to pull a lot of air into the case. What temps do you get on the GPU while running games?
Asked by: Brackenwall
The front pannel is not a door - its fixed. The case pulls air in from top and bottom of that pannel. I have 2x 140mm fan pulling air in and there is no issue at all - I use High Static presure fans to pull air through the front dust filter and the air flow is really good. I run a GTX 1070 and it reaches maybe 64c in games. So I dont see any issue with the GPU.
