Inside the CMT340
With an unimpeded view of the interior now at hand, we can see the two section design with the PSU cover keeping the PSU and HDD cage under wraps. The section above holds the rest of the components, where the hardware, manual, and wiring is now tied for transit.
The front of the chassis has three fans pre-installed behind the glass, without any form of a dust filter. If you wish to change the fans, you will need to remove four thumbscrews from inside of the chassis, and the glass can then be removed.
The top of the chassis has slots to mount 120mm and 140mm fans, but also notice that the 120mm mounts are pushed as far to the left of the case as possible, to help alleviate constraints some RAM and motherboards may case a 240mm radiator installation.
The motherboard tray offers a large access hole, it has fourteen wire tie points visible, and another three blocked from view by the fans. The motherboard tray is not labeled, but all of the standoffs are installed for an ATX motherboard.
The PSU cover is well ventilated across the top of it, and is where the pair of dedicated 2.5" drive trays are located. There is a hole at the back to pass some wires through, but the gap at the front is to allow for liquid cooling support, but you do have to move the HDD cage we can see blocking it now. On the side of the cover there is the FSP logo along with an open area to allow a view of the PSU sticker.
The last of the matched set of four fans is found hanging ion the back of the chassis. We also see the ventilated expansion slot covers, and since they are accessed externally, we cannot see the 6/32 screws used to secure them.
Behind the motherboard tray, we see a fan hub, which controls the RGB and fan power, either with the switch on the chassis, or by connecting a 4-pin RGB connector to the motherboard. The motherboard tray is angled near the front, to allow better access to ports, but does limit any chances of using an EATX motherboard.
At the front of the chassis, under the PSU cover is the two bay 3.5" drive trays. The drives install with connections facing out this side, and the entire cage can be removed or slid to the right of where we see it now. These trays are also drilled for 2.5" drives to fit.
The room at the back for the PSU and the wires that go along with it is limited, but the area is well ventilated and has rubber pads for the PSU to rest upon. We do advise connecting modular wires to the PSU before sliding it in through the back, as the tall frame on the side limits access for larger hands.
From the front of the chassis, there is the USB 3.0 and HD Audio connectors at the top. At the bottom are the wires to connect the HDD activity LED, the power LED, and the power switch. What we did not show here is the 4-pin Molex connector that is used to power the fan hub.
