This is my first micro atx build and the main reason why I decided to do it is the unique look of this case. Most other small cases have that cube look which is not my style so this case really stuck out. It is rather small (which I like) but still has plenty of room to work with. It's also lightweight and perfect for portability. All my previous cases never had enough space in the back for cable management but this case has plenty of room to spare (a regular hard drive can be mounted back there). There's also 2 slots for SSD's.I'd consider this case to be a great deal because of the 2 included RGB fans which can be a little costly on their own. The case also has a nice quality to it and I like that it takes a regular atx power supply. What makes this case really shine is its customization options. The rubber on the thumb screws allow it to be laid on its side, and the I/O panel can be moved to 6 different locations. Airflow doesn't seem to be bad despite it looking like the acrylic panels would choke the system, but there is a vent that allows the air to escape. Check out the images to see how small this case looks compared to a full tower.Now here are some concerns. You have to be very careful not to scratch the acrylic panels, especially when wiping off (They attract dust). My case arrived with some abrasions on the RGB shroud panel at the top front of the case but it's not too noticeable. The removable handles are made of a hard rubber which is great for traction but dust can cling to it rather easily. I really do wish they had an option where the customer can upgrade to the full 4 RGB fans with the appropriate hardware, but that's just what I would like considering the images for the product show both panels occupied with fans. Also I should note that one of the holes in the metal frame that holds up the acrylic side panel was a little too small and I needed to thread it simply by using a screwdriver to force the screw in straight.To cycle through the RGB modes they suggest sacrificing the reset switch to plug into the rgb controller, but pressing the button on the RGB controller box also cycles through the different modes and colors. You can also buy a vandal momentary switch and create your own reset/RGB cycle button if you're up for a little modding :).I debated whether or not to knock a star off for the minor cosmetic blemishes but it's not really worth it. I'd highly recommend this little case.

Pro:This is the first computer I have built and in all my searching for a colorful and attractive but versatile and durable case… this is it. Easy to handle or love but color fun is amazing.The handles are an added feature I have learned to really appreciateButtons and all looks great very high endCon:One draw back and this may be on me is that there was no mounts inside for the parts so I had to invent something myself to protect the parts and hold them where they needed to be. If anyone knows why this was left out would love to know.Second draw back is the screws in some places didn’t fit quite right but easily got some of my own that did.All in all very pleased

Pro:Pretty good case for the price. The LEDs have tons of settings and the plastic clear sides look good.Con:I didnt like the fact the remote for changing the LED lights had to be stuck inside the case itself. Its wired directly to the psu and impossible to have outside the case.

For the price, I am a big fan of this case - on the caveat that I am not over locking anything in my system. As others have stated, airflow is not good on this case. The holes and the plastic cover on the front are not big enough for sufficient air, thus this case subjects your components to higher temperatures. The looks are great, though. The included RGB fans look amazing and the "modularity" of the case is nice as well. I had to take one of the top handles off in order to fit it under my desk and it came off with ease.Pros:Good looking caseIncluded RGB fans"Modularity"Polished interior and exteriorCons:Terrible airflowThe "handles" center the weight so it might be easy to knock over your PC with enough forceOnly one 3.5" drive bay - a small complaint since this is mATX but another one would have been cool.
