Cooler Master N400

The N400 is a member of Cooler Master's all-new N Series computer cases. All members of the N Series feature a mesh front panel that provides modern styling and optimized ventilation. Water cooling is fully embraced as the N400 supports up to 240mm radiators for extreme cooling performance. Multiple dust filters located throughout the chassis make system maintenance simple and convenient.

Superior Ventilation

Excellent Water Cooling Support

The N Series features a premium, fully meshed front panel that allows substantial airflow to pass through the chassis. Strategic placement of the included fans provide optimum cooling for internal components out of the box.

Flexible mounting options including support for a 240mm radiator along the right side and 120mm at the rear.

Simplified Cleaning and Maintenance

Optimized Storage Space

Multiple filters can be found throughout N400 (top, right, bottom) to make cleaning dusty build up a breeze.

4 out of 5 eggsGood reasonably priced mid tower case

Pros: * Simple black look.
* Easy to build in.
* Decent cooling for basic system.
* Seems well built for the price
* Screwless HDD/DVD mounts
* Front USB 3

Cons: * Dust filters don't come out.
* I am not sure I'm going to end up with positive pressure without moving included fan around.
* Case fans aren't the quietest, but stock CPU cooler is louder anyway.

Other Thoughts: For the simple gaming system I built in this I would have preferred to use the same TJ08 I have for myself, (better cooling, completely silent, removable dust filter, and smaller), but this saved a few bucks which mattered more for the person that's getting it.

It is easier to build in, works fine, and has a little extra space.

5 out of 5 eggsHell yes.

Pros: Simple, yet stylish. front panel has two USB2.0's, and two USB3.0's. A perfect sized mid atx tower. I'm overly satisfied with the purchase of this case. It adds more room on my computer desk compared to my old clunky, "Transmormers" themed, NZXT Gaurdian 921(yuck.). Mesh panels make a thorough airflow through out the tower, It's Cooler Master. after all.. Provides an optional water cooling mount, which i thought was neat. Including support for a 240mm radiator along the right side and 120mm at the rear. Includes lot of drive bays, and filters all over the case!!! Last but not least, at the time of the review, the case was only 59.99!!! with mail in rebate its only 49.99!!!

Cons: non

Other Thoughts: In my opinion, could use a windowed side panel.

3 out of 5 eggsGood basic case

Pros: Attractive, simplistic design, USB 3.0 and 2.0 ports on the front, reasonable cable management. Plenty of fans and a clean air flow. It came with all standoffs, cable ties, and a range of hardware.

Cons: Loud fans, s a little flimsy, some screw holes aren't placed correctly, the motherboard connections could be better and its not tool free.

Other Thoughts: Descent overall case, I wouldn't seek it out again, but its not worth the hassle and expense of returning. I'd recommend passing on it unless you get a good price.

4 out of 5 eggsExcellent Entry Level Case

Pros: Light weight, but very durable. Excellent build quality. Very quiet. Airflow is adequate. SSD bay on the side, of the case.

Cons: It's been 10 years since I last bought a case, and while this one may be adequate for me, this case might be a bit small for enthusiasts who are looking at the larger offerings from manufacturers like Corsair.

Also, the one thing that drives me crazy about this case is the PSU filter on the bottom. You have to remove the PSU in order to remove the filter. Small problem, and I didn't have a psu filter before.

5 out of 5 eggsUpdate to original review

Pros: - Looks great
- Uber Fan Slots
- Cheap
- LOTS of hard drive space!!!

Cons: - Plan out your angle of attack, as far as your fans go. It's been a few months since I finished my build, but I believe the two side fans should go in first, then the front two, then everything else. If you put the front two on first you may have to back track to get in the two side fans.

Other Thoughts: I bought this case to match up to the ASRock Fatal1ty Pro LGA 1150 Intel Z87 motherboard and my PCPC Silencer MK II 950W Power Supply. This reason being that this tri of fun can really take MASSIVE amounts of hard drives!!! If you are a collector of many space demanding things, this build is for you. So far I have one 256gb ssd, one 500gb hdd for backup, and so far two 3tb hdd and another on the way. That still leaves me with 7 more 3tb hdd or higher I can put into it. Yippy! And in all seriousness, 3tb hdd are getting really cheap these days. So it baffles me to see that people pay so much for the little ones. Heck, even if you catch an external hdd on sale for cheaper just rip the harddrive out of the external case and slap it in the comp case.

5 out of 5 eggs

Pros: solid feel, stylish, usb 3.0 on front panel, comes with 2 fans but can accommodate up to 8, no bracket need for 2.5" drives, good price

Cons: none

Other Thoughts: One reason I got this case was because of the usb 3.0 in the front, many of the less expensive cases don't have this yet. It's larger than I expected but there's lots of room for expansion - I may set up a RAID as it holds 5 3.5" hard drives on top of the 3 2.5" drives. Some people commented that their cases were damaged when they got them, but mine was packed well and arrived safely.

4 out of 5 eggsGreat case, but...

Pros: Sturdy case, plenty of airflow, not too big, simple look.

Cons: The only reason I had to send this case back is because there was not enough room between my mobo and the case at the top for the Corsair H100i.

5 out of 5 eggsGreat Case

Pros: Really solid case
Great price

Cons: No wiring system
No fancy looks

Other Thoughts: This is really solid case for the price especially if you get it on sale. Has a lot of fan slots, full metal case, plenty of spaced for multiple HDD, Disk Drives. Only beef with the case is that it doesn't have room on the backside of the case for cables and has a poor cable management system in general. If you're concerned with clutter consider a modular PSU. However considering the price it is a very good case. All in all if you need a solid case which case house all your parts this is the case for you!
