Would this be the right case for me?
New and experienced users alike will find building with the NZXT S340 easy, thanks to a variety of cable management options and its cooling potential. The optical disk drive (ODD) free design means that despite its compact size, the interior of the case is spacious. An integrated power supply (PSU) shroud/cover and cable management bar supply you with areas in the case to hide messy cabling, helping you quickly and easily create an ultra-clean build look. You can route your cables to these areas through the various grommet-less holes and utilise one of the twenty plus cable management points to hold your cables in place.

A 360 degree steel casing surrounds the all-steel chassis to provide you with durability, and a good sized window on the side of the case lets you see inside. With the great cable management possibilities you’ll be able to show off a sleek and smart interior that you can be proud of. There is plenty of space for hard drives or solid state drives (SSDs) too, with two 2.5-inch bays located on top of the PSU shroud, two 3.5-inch bays covered by the shroud and a further combo bay located underneath the 3.5-inch bays.

What is the cooling potential like with this case?
A total of five fan mounting locations at the front, rear and top of the case gives you superb cooling potential. Pre-fitted are two exhaust fans at the rear and top of the case, leaving you with the option to install either two 140mm or 120mm fans at the front. A magnetic fan/vent filter is also located at the front of the case, to keep dust intake to a minimum and provides easier cleaning too. Another filter is located at the bottom of the PSU vent. This case supports water cooling, with it able to accommodate up to a 280mm* radiator at the front of the case or a 120mm radiator at the rear.

*You may only be able to install a single row of fans on the radiator, due to the cable management bar

What connections are provided?
The top of the case has two USB 3.0 ports and HD audio (microphone and headphone port), for ease of access to files stored on portable USB drives and connecting headsets or any other USB device. Please note that the S340 doesn’t have a dedicated reset button.
