The NZXT S340 is a mid-tower computer case that comes in two colors: black and white. It includes a side panel window plus options for water cooling, a support for a 140 mm fan on top plus a back 120 mm and dual; there are also 140 mm fans in the front.

The case comes with a box that contains all of the hardware needed for installation. The front, sides and rear parts of the case are coated with a semi-shiny black paint.

It does not have an external drive bay and it features a minimalistic, simple and clean design.

The rear part of the case includes a semi-shiny finish too and you will see many ventilation holes on it. There is also an opening on the thumbscrew segment of the PCI slots meant for easier unscrewing and screwing.

The power supply is installed from the rear part—you have to take away the rear frame and screw the item on the PSU then slide the PSU behindhand. The power button along with the two USB 3.0 ports, mic and headphone ports and HDD activity signifier are positioned on the front top segment of the casing.

The top part of the case does not have a shiny coating but it does have a good matte black finish. Under the case are four feet that are sufficiently tall for providing clearance from the ground.

You will also find a removable dust filter on the bottom.

Inside on the lower part is a shroud that covers the power source and the cage for the hard drive. The shroud has removable slots for two 2.5 inch SSD on top plus two 120 mm stock fans that are built in on the top and rear segments.

The back part of the motherboard tray has several cables for the front I/O ports. You can install two hard drives from the rear part where the power supply comes from and you will also notice ample room for accommodating power supplies that are longer.

What we love about the case, apart from its professional and minimalist design, is its focus on what is installed inside it. We did not have any problems fixing parts inside it. Also, the top matte finish is actually handy since you can put items on it without them sliding or falling about.

Cable management is also made simpler by the S340 since there is sufficient room for all cables and you can easily conceal them at the back of the motherboard tray. It is more affordable compared to other cases from the brand too.


Some customers complained about the hard drive cage due to it being tool-less. The case does not have anti-vibration pads for the HDs and there are also no means to cool them down.


The NZXT S340 Mid Tower Computer Case (Amazon link) will keep everything organized inside and it is one of the most affordable mid-tower PC cases in the market. However, if you are concerned about cooling down hard drives and anti-vibration items for it, you may have to look for another case.
