This case is pretty sweet for the price. Its interior is easy to work in and mounting anything is a breeze.

My only gripe, is that there are no top fan mounting positions so you're only limited to a single exhaust fan which can be a problem if you have a CPU that tends to run hot.

WOW. I have built in many cases before, but none can even touch this one. The cable management space, modularity, and looks are those of a $100+ case yet it's only $60. Thoroughly impressed.

Decent case with decent build quality, except....

You shouldn't need the manual to build a computer.

After a few builds, you don't really need it. But this case would be a nightmare for first time builders, simply because of the lack of a somewhat better manual. You may as well throw the manual out the window, cause it's not like you're going to learn much other than how many screws there are and what everything is.

No, I didn't forget to mention that it tells you what the screws are for. That's because it doesn't tell you that. No mention of threading, even.

Also, there are some motherboards with the need for more standoffs than this provides - such as my ASRock 970A-G/3.1. The case only gives you 7 standoffs, but gives you 13 screws for the motherboard and whatever else in the case uses these screws. I needed 8, so I grabbed the box I had with the Cooler Master N200's screws and standoffs and grabbed a standoff and screw so I would have all 8 installed on the board. Imagine being a first time builder. Oh well, not enough standoffs. They don't have any spares from other cases. Then this supposed first-timer might be scared of not enough standoffs being installed.

On top of this, they also don't tell you how the fan mounts in the front worked. I ended up stripping one of the original fan screws from the back fan when I moved it to the front because I couldn't figure it out at first. I guess they were assuming you would look at the other fan to see how to install it first. They seem to make you imply and guess a lot.

Ironically, even the N200 (which is $40, $20 cheaper than this) has a better manual, and is made by the same company, but released 3 going on 4 years ago.

Seriously Cooler Master, I feel like this wasn't completely thought through. Mainly the manual is the reason for giving this only 3 stars.

I'm really Happy with this case, it's really big and allow super large cards, a lot of cooling options and it's modular.

This case is annoying. It has great airflow, but I just want some more quietness in my room. It's a decent case to work in; it has plenty of tiedown points, decently sized cable management holes (and plenty of them), and it has a removable PSU shroud. None of the screws are properly labeled, however.

Great case to build with, a lot of HDD and SSD ports, 2 front USB 3.0 connections, and it comes with 2 fans.

Can’t get a better case for £35! Dust filters everywhere except for the back fan which will always be blowing air out anyway. Loads of room for cable management, spacious inside for better airflow and overall, pretty good looking. Not a glass window, however still looks great and if anything, it means I wont break it.

Pretty case, nothing fancy. No space for optical drive if that’s something you need but I don’t use disks anymore personally. Got it from Newegg for $35 after rebate and definitely good for my money.
