NZXT S340 Mid Tower Chassis Review – Best Case under $70?


To open the case there are 2 thumb screws on each side, which are captive and stay in place when the side panels are off. This will make searching for thumb screws after opening up the case a non-issue.


Inside the case we can see the NZXT S340’s separated chamber design, making cable management easier and helping airflow throughout the case.

The chassis supports Full size ATX, Micro ATX and M-ITX motherboards and a nice big cutout for installing aftermarket cooling. Although the clearance for CPU Coolers is only 161mm or 6.33 inches. This is barely enough for the Hyper 212 Evo, one of the more popular CPU Coolers available. The Phanteks PH-TC12LS that we reviewed recently will fit fine as will most low profile CPU coolers. Graphics cards up to 364mm can fit without a radiator in the front.

Moving on NZXT also has this bracket for keeping cable management tidy, although you won’t have to use it (we didn’t to illustrate this point) as there is more than enough space to hide the cables in front of the PSU.

There is support for 2 3.5 inch HDD’s in the cage here and a 3rd one below the cage mounted to the bottom of the case directly.

The front can support 2 140 or 120mm fans, the rear supports a single 120mm fan and the top supports a 140 or 120mm fan. The rear can support a single 120mm radiator like the Kraken X31 and the front can support a dual radiator like the Kraken x61 We would recommend using water cooling as this case was designed with radiators in mind.

Today we have privilege of looking at the NZXT S340 case, which while the original Phantom cases were less then impressive, we were looking to the S340 to make a bold statement. The S340 is a case that wants to make a statement about what you can get in a value case. NZXT has recently been making a strong push into the case market, against the likes of Corsair, Cooler Master and Fractal, with its recent H440 they have taken a strong hold in the chassis market. As system builders we have a lot of experience in what to look for in a…
