5 out of 5 eggsMoney well spent

Pros: It's solid, tons of cable management, carrying handles are nice, neat things like the thumb screw power supply mount and the super easy to swap hard drive mounts are nice, looks really nice.

Easy access to pretty much anything in the case.

Cons: The 200mm fan mount on top does not a fit a normal 200mm fan, you need to have a fan with the the offset mounts. Not really a con but the fan I had did not work.

Other Thoughts: I used this for my gaming rig and it's keeping the internal temp about 10 Celsius cooler than my previous case and with the intake layout and the two fans up front both my graphics cards and CPU radiator are staying considerably cooler than any standard case I've owned.

5 out of 5 eggsGreat case

Pros: This case is really well designed. Anytime you are working in it, whether building your system or upgrading, it provides easy access to everything. Power supply underneath to clear some of that clutter, tons of spots to tie down loose cables, well ventilated, easy drive insertion/removal; its got everything you need in a case.

Cons: It is a little pricey at $100+ but its definitely worth it. Its also quite bulky, but since most people just stuff it under a desk anyway, probably not a big issue.

4 out of 5 eggs

Pros: Great case. Looks great and is incredibly well built.

Cons: Had surprisingly little airflow in my build until I added 4 fans, but I think that was more my paranoia than the case actually needing 6 fans at once. (I also just wanted pretty purple fans)

5 out of 5 eggsA cool idea for the Cooler Master Team!

Pros: I love this thing so much. It's my companion cube. Not that I would slap some heart stickers on this. Anyways- My suggestion for this cube is to make the hot swap bays removable/modular. Like, just in case, for those of us that want the extra drive space, but don't want to give up the really cool dual hot swap bays permanently.

Cons: Nothing yet, it's not an enclosed case like other cases, it'll run like a furnace with my FX8350, but if you live in colder climates, that would be awesome. I live in LA so it's a little hot. Also, I hear you can't stack these? WHY NOT, I don't have two but if find somebody at a LAN party, I know i'll try to stack them.

I guess sometimes I wish i could put in more drives? I always thought it would be awesome if the hot swap bays were removable, and it's not like I'm lazy either, i'm going to try to dremel the part I want off and just the mod it myself. But you know, for future updates.

Other Thoughts: A really nice box for your socks

Good job Cooler Master team!

5 out of 5 eggsgreat case

Pros: great case everything is a plus

Cons: the silly hotswap bays... i like em but i cut the housing for the top one so i could put a 3.5 card reader/ fan controller in and still use the bottom

Other Thoughts: the 20cm fan is overpriced especially the solid black one
neat freaks work nightmare since its HAF there could be lots of dust

4 out of 5 eggssweet case... nothing perfect

Pros: Nicely styled case something different and unique compared to the average tower. Setting this case up was nice you could put everything in the case or not before the motherboard tray. Making it easy to test the mb, cpu, and mem before actually connecting everything

Cons: only one really not against the case just bad draw and cost of return shipping... one of the front usb 3 ports was broken when it arrived. Sorta annoying but nothing i can't live with

Other Thoughts: if you get one with the front usb working without having to rma... something i don't do for a port. I would say buy i will warn you its a beast of a case

5 out of 5 eggsGood changes made to this case over the original

Pros: I read through all the reviews on this case. I was at first concerned about some of the issues like the hot swap bays frying hard drives. This was due to a Molex power connector that some people were forcing plugged in the wrong direction. This connection has been changed to a Sata power connection, and there is no longer a possibility of plugging it in backwards. This is a good improvement.

I like that they've changed the 4-bay 2.5" drive bay to a dual-bay 3.5" drive bay. You can get adapters to put two 2.5" drives in each bay, so people with a lot of SSD drives can still do that, but people like me who have only one or 2 SSD drives still have plenty of room for large data storage drives.

This case gives me plenty of airflow where I need it. The case was well thought out and well designed.

Quality of build is excellent. The PCB back plane for the hot swap bays is actually done quite well this time around.

Customer Service is top notch. My case actually came missing 2 anti-vibration retainer pins for one of the hot-swap bays, and they are sending me a whole new bay for it. I guess I'll have a spare if one ever breaks.

Cons: Bill Gates still hasn't sent me that check for 50 Billion US Dollars I asked him for. It was for a good cause, too! "Cause I wanted it!"

Other Thoughts: Make sure you have your build well planned before you start. If you have a large, heavy CPU Cooler or if you have water cooling, then you'll want to make sure you get the bottom installed properly before you put in the motherboard tray. Otherwise, you'll have a more difficult time removing it with the cooling hoses and all when you have to access something on the bottom that can only be reached by removing that tray again. Lots of things can be reached from the sides, but you better have your SATA cables plugged into the hot swap bay PCB before you put that motherboard tray down, etc.

This case should be standard issue for anyone that opens their case to tinker on a regular or even semi-regular basis.

Just waiting for my new 200mm Blue LED fan to arrive so I can light it up.

5 out of 5 eggs

Pros: This case is VERY sturdy. Don't be fooled by the plastic front, the frame is very ridged. The carrying handle are also very sturdy and makes me much less worried when I have to move my case. Also the side panels come off very easy and allow great access to core components. Plus air flow is great. I got this case because my SLI setup would warm the most ventilated case even with many Delta 250 CFM fans. Now I can run silent fans and get better temps. I cannot stress how good air flow is. Hot swap is nice I don't really use it but some people do, I've had no issues, just make sure to plug everything in correctly.
Everything can come off of this case. Everything. All of the trays, cages, mounts and motherboard tray.
Plus for me the red power led and HDD led look nice.
PSU can easily slide out for more room to stick your hand in and manage cables.

Cons: Fan mounts are limited. Behind the front there is only room for 25mm thickness fans. The top only has the one mount, 200mm is not really standard. I have a 230mm but the sides are cut off. Just buy the case and look and measure before you buy a fan. Also I'm disappointed the the fan above IO is only 120. It would be nice for a 140. Also mounts on the side would be nice.
My biggest complaint is the cable management. The bottom is very very very cramped. I had a very hard time routing my cables. Please put in components in an order that you can plug in. I suggest putting in PSU last. I know I should be so upset about the cables they are very out of airflow but to add cables is difficult. Because of this cable/space issue it took me over twice as long to set this case up. So I would only recommend this to someone that is willing to take the time or is use to small system builds.

Other Thoughts: I'm not complaining but please be aware. This takes up much more desk space than a normal case. Also I ran graphics card length issues with my radiator. Just look up dimensions before hand. I thought I could make it but I was off my half a centimeter and it was a gut wrenching feeling to be so close. However I have a 38mm rad and a triple fan GPU, but please measure first.

Some people have issues with the power button. I did not but I can see where a problem could arise. It's a simple fix and anyone that should have this case can fix it. This case is for someone that demands great airflow, portability and extreme modulation. Don't get this case for an average user it is too complicated.

Pros: Looks good. Been looking for a non-tower case because my computer sits on a shelf above my monitors. This case looks like it would fit the bill. I haven't purchased the case yet because I want the top window version but I am unable to find it anywhere. I even posted on Cooler Master forum and got a "I'll check on it" response...then nothing. Not sure I will purchase his or not.

Cons: Can't find the top window version

5 out of 5 eggsExcellent case

Pros: Motherboard is parallel with the floor limiting the strain on video cards without a back plate.
High air flow with minimal noise produced from fans.
Hot swap bays make swapping out 2 of your hard drives very easy

Cons: Top panel can't have a fan mounted on it when you have a large CPU heat sink such as the hyper 212 evo.
installing hard drives isn't as easy as it could be(other then the hot swap bays)
Wish it had more room for additional hard drives.

Other Thoughts: Overall this is a great case that works better then many mid and full tower cases depending on your use.
I have mine sitting on the floor under my desk and often use it as a foot rest while playing games or watching Netflix.
