Source 340 Midi-Tower Case - Blue Window

The Source 340 comes with the standard accouterments that you would expect from a premium case, such as USB 3.0, filtered intakes, a PSU shroud, and quality materials and is easily one of the most durable cases we've ever made.

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. With 90% of the case being steel, we’re able to deliver superior durability for a case you can keep build to build.

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.

Top-quality little tower

I was very impressed by this case. It's small in stature, but has all the room you need for a 280mm radiator (Kraken X61 slots in nicely). I think you'd struggle to make a full ATX case any smaller than this. And yet, it still feels roomy.

Cable management is plentiful, and the hidden cut-out to behind the mobo tray is a stroke of genius. Lots of other cut-outs make life very easy. The result is a very clean build that I'm proud to show off.

Tool-less design is a plus, along with easily-removable dust filters. There are lots of other little things that NZXT has done that make installtion an absolute joy.

The only issue I had with this case was that the mobo was a tight fit, and the IO was pressed up very tight against the IO shield plate. This also meant that expansion card screw holes didn't quite line up right, but I got them in with a bit of wiggling. (I used an ASUS Maximus VIII Hero, your mileage might vary.)

However, all that said, this is a great little case packed with features, and you can't fall down for the price.
