The Cooler Master Masterbox NR600 is equipped with one 120mm fan in the front. You can install up to three 120mm fans, or two 140mm ones instead. This amount of space is enough to fit even 360mm radiators. The front mesh also doubles as a dust filter.

As you can see, there is about 70mm of space in the PSU shroud cut-out, so you can mount standard AIO radiators (with fans that are typically 25mm thick) in the front, but if you want to use some beefier ones (or a push-pull setup), you can still do it, as the front fans are mounted on the front of chassis frame.

The back side of the Cooler Master chassis is clean, and it should be relatively easy to route all the cables properly in there, especially that the cable openings with rubber grommets are slightly angled, so you’ll have a bit more space on the left side of this area.

Clearance varies depending on where you measure it. It’s in a range between 20 and 28 mm, and the latter value is quite nice.

On the lower-left side, there is space for up to three 3.5” drives. The standard cables include USB 3.0, and front panel connections (with HD audio), as well as one SATA connector (for the fan hub). The cabling is black, which improves the aesthetics of the whole package. There is no fan hub included (but that’s not a problem considering the budget).
