5 out of 5 eggsGood looks, great cooling, and potential.

This review is from: Cooler Master N400 NSE-400-KKN2 N-Series Mid Tower Computer Case with ATX Motherboard Support, Multiple 240mm Radiator Support, and Ventilated Front Panel

Pros: Great venting, Has removable hair guards. great if you have pets that shed. came with all required mounting hardware.

Cons: Instructions like IKEA, no reading, they tried to have me use a corse thread screw for the motherboard, the studs are fine threaded. Instruction misprint.

Other Thoughts: Easily fits MSI GTX 980 TI 6g.
I built a CUSTOM MOUNT out of scrap aluminum, and put an H90 140mm Corsair liquid cooler into it, with no cutting or drilling of the case.

3 out of 5 eggsNice compact full ATX case for basic builds

This review is from: Cooler Master N400 NSE-400-KKN2 N-Series Mid Tower Computer Case with ATX Motherboard Support, Multiple 240mm Radiator Support, and Ventilated Front Panel

Pros: Modern, clean looking, compact size for atx boards. I was looking for a simple no-frills compact case, this case was exactly that.

Cons: Build quality seems a bit cheap compared to other cases (such as the define R4). Tool-less hard drive bays are laughable cheap. The 2.5" mount is cheap and does not fully secure drives, it gets the job done however.

Other Thoughts: Overall, I like this case for the price. It looks sharp, and for a relatively simple build its a solid choice.

3 out of 5 eggsOk product

This review is from: Cooler Master N400 NSE-400-KKN2 N-Series Mid Tower Computer Case with ATX Motherboard Support, Multiple 240mm Radiator Support, and Ventilated Front Panel

Pros: Solid case
Spacious for my needs

Cons: Front panel paint started chipping after a few months
Front panel Usb 3.0 failed within 2 months after purchase

Other Thoughts: I would recommend to those needing a cheap case. However I would recommend to the manufacturer that the paint and front I/O was should be made a little sturdier.

4 out of 5 eggsGreat case for starters!

This review is from: Cooler Master N400 NSE-400-KKN2 N-Series Mid Tower Computer Case with ATX Motherboard Support, Multiple 240mm Radiator Support, and Ventilated Front Panel

Pros: Absolutely love this case!! I love how many fans you can mount and the airflow from the front. It seems to be a great case with no issues so far with my build.

Cons: Wish there was a window option with this case.

3 out of 5 eggsI like the case, but...

This review is from: Cooler Master N400 NSE-400-KKN2 N-Series Mid Tower Computer Case with ATX Motherboard Support, Multiple 240mm Radiator Support, and Ventilated Front Panel

Pros: Plenty of ventilation
Decent wire management
Plenty of room for expansion
Front panel connectors are long
Looks nice

Cons: Front panel connectors are REALLY long. I could easily connect them to another PC outside the case.
Recessed pan for MB - See other thoughts for reason

Other Thoughts: I bought this to house the Asus Z77 Sabertooth MB I took out of my old Antec 900 case because it's a solid mb with 32GB of RAM and a good I7 processor already on it. The mb installation went well until I tried to install my USB3.0 front panel connector and SATA cables for my drives. The recessed pan for the mb seems like a great idea unless you have sideways facing data ports. I can't connect the USB3.0 cable at all, and can only use the topmost row of SATA ports. The pan is THAT deep. I guess I'll try to find some kind of right angle adapter for the USB cable or just not use those ports. I could try 90° SATA cables, but I don't see what it would since they would just block access to the port next to them, so no difference.

I really wanted to like the case, and it's not Cooler Master's fault that Asus uses odd connectors, but I wish I'd known ahead of time. I've had the case for some time waiting to have the time to build the PC and now...

5 out of 5 eggsperfect case

This review is from: Cooler Master N400 NSE-400-KKN2 N-Series Mid Tower Computer Case with ATX Motherboard Support, Multiple 240mm Radiator Support, and Ventilated Front Panel

Pros: I think this case is a sleeper compared to what's out there and the "normalness" of it combined with its performance! give it a good look and compare. you won't find a better case if this is the type of case you are interested in.

Cons: none, absolutely none

Other Thoughts: I still ponder how companies can produce such items for such little cost to the consumer.
