Cooler Master N300 (KKN1)

Standard housing to be improved

The pluses :
- Functional
- Nice mesh
- Numerous 3.5" slots with 3 quick release clips to best fit your cable length
- Two large fans included
- Ventilated top for watercooling (not visible on the pictures)
- Vented on the bottom for non-fanless power supplies (not visible on the pictures)
- SATA connection proven to be much easier on the axis of the case than on the side (ex: Fractal Design Core 2500)

Minus :
- Sloppy manufacturer: a door screw was forced and the door deformed (obvious 1mm opening corrected by tinkering), and a big 30cm grey exterior trace that doesn't go away
- Horribly difficult to tear off the front panel: I had to take a tool, damage my finger and just miss tearing off the front USB ports
- The 2 horizontal SATA ports on my motherboard are unusable because of the shape of the metal sheet (straight wire) or the graphics card in front (bent wire)
- The only position of the SSD is too low for the power cable unless it is terminal or dedicated
- Why is there still an unwired front slot for a USB socket?
- Price waltz for this average but effective product

Fair

The weight and the brand Cooler Master let us think that the hardware was serious, and the disappointment is great. The screws and bolts are catastrophic and I had to replace everything. The 3.5 discs with tool-less fasteners are well designed, but for the 2.5 discs, you'll have to tinker or buy additional hardware. One of the last models to accept a DVD drive, which is why I chose it, and that too is well done. The fans are useless because they have meshes on all sides, and the air gets through as much as the noise. For 50€ OK, for 70€ not.

Very good box for the price

With a contained size, this tower allows the passage of large ventirads such as the Noctua NH-U12S and its 158mm height as well as graphics cards of all formats (by sacrificing a few hard disk bays). It is necessary to make the connections and the assembly in the right order (hard disk drive before the graphic card for example) otherwise you will have to reassemble some elements (it happens to very good people you know ^^).

In the end, the result is very satisfying, for those who want a sober tower with a reasonable budget.

Finally, a little advice to have an "optimal" ventilation, in order to fan all the disk bays, the purchase of an additional 120mm fan will be perfect to support the one already provided on the front (a 140mm fan is possible but it does not cover the whole height and condemns the installation of 2 120mm fans).

Very functional and spacious. Allows for clean assembly.

Very happy with my purchase, the case allows for proper cable routing.
The front panel requires a bit of roughing it, but it went well.
Only two minor negative points:
- This is the model with only 1 USB3 port, so you "lose" a USB3 port on the front.
- The PCI-E port brackets have to be removed from the backplane. If you remove a PCI-E card, it leaves an unsightly hole.

Very good box for an affordable price

For 50€, you have a good case, very well ventilated (up to 9 fans ^^)
Two fans are provided (quite noisy though, but very efficient).
A dust filter is present for the power supply, but I doubt that it is effective given the size of the mesh...
There is only one USB 3.0 port, although the cable can carry two.
I couldn't figure out how to remove the front panel.
The structure is quite flexible, the case is not made to be carried often).
The case itself is relatively light.
It comes with all the necessary screws and bolts!

Very good box

Very good box which replaces the "Elite RC - 310" of the same brand.
The pluses :
- Slot for 8 fans, enough to create a real tornado
- Slot for 8 3.5" racks
- Enough to fit an SLI without worries
The minuses :
- the 2.5 slot at the bottom of the case => impossible to connect the sata power supply...
- Case tends to vibrate when 8 3.5" hard drives are used (due to the numerous ventilation slots)

I'm just taking off 1/2 star for the 2.5" slot which is badly designed.
Other than that it is really perfect.

PS: for an AIRcooling configuration, the flow management inside the bug is a real headache.

top of the line

A great box, I bought it for an office configuration for the moment but with the optics of up in gamer, the place is impressive and offers us a great facility to install any type of component, a super reactivity of the service LDLC

Good box

I bought this box to fit my new setup, and for the price, it's great.

Only the management cable is a bit of a hassle but with a bit of imagination it all fits perfectly.

I highly recommend it.

Very functional case

Personally, I appreciate this kind of sober and functional case.

The + : 1 USB 3 socket on the front, spacious, power supply in low position

The - : the 2.5" slot is not really usable in the bottom of the case (impossible to connect the SATA power plug on my SSD, I had to buy a small 3.5" adapter)
