Excellent case, very well made, very easy to work with.

I've owned a lot of PC cases through the years, and this one is definitely one of the nicest. The fit and finish is excellent, and it's very sturdy. There is a lot of flexibility in how to set up the internals, and I was able to easily fit a dual Xeon ATX board in with plenty of room to route cables and install a full load of PCI-E cards and multiple SSDs and an HDD drive. Ventilation is excellent - I built a workstation, not a gaming rig, so I am not taking advantage of the top and bottom fan mounts, but it's nice to know I can if needed. Read more

Cooler master Qube 540

I love the design, a little modern, a little apple, a little industrial. ATX support for motherboard and PSU. Cooling is performance is great. A little Issue i had was not so clear mounting instructions for at the ATX psu (bottom mounted) and another issue i have is the fan mounting plate is warped and causes both 140 or 120mm double fans and to have vibration/humming sound. I have 2 different fans. Wonder if cooler master could send me another one of the fan mounts thats not so warped. Read more

Pain,and painful to assemble.

Is okay, but case is a nightmare for cable management. For oversize GPU is a tight fit. The psu mounting kit only designed for old school layout psu, if you have a Corsair RM 850xshift, you have to plug in the cables and squeeze it in. The mounting bracket screws is too small, especially for the front I.O panel and 360mm aio mounting bracket. 2.5 SSD mounting is okay but buy M.2 instead to save you the trouble for wire management.

No for first timers, Yes for vets

The build quality here for a budget case is unmatched in material selection and ease of transport. However cable management and path selection for wire aesthetics is unbelievably meticulous, and RIP any beginner who wants a sleek looking case display. 5 of 5 for expert value. 3 of 5 for a beginner or casual builder.

Nice Case

This case is pretty durable and I'm excited to see what 3D printed parts Cooler Master and the community will have available to build on! Only complaint so far is that cable management is a little tricky, you do have to take some time to really organize the cables. The backside does offer some space for zip ties to help with cable management. The whole case except for 2 small openings has dust filters which seem pretty easy to get to for cleaning. The case has plenty of airflow. There's room for 2 120mm fans on the bottom for intake air, 3 fans on top, and 1 fan on the back for exhaust fans. Hopefully, the inside will look better after taking some time to cable manage. Read more

Great Cooling, Not good for first time builder.

Nice modular design. Definitely takes Thinking on component installation, to another level when building a new pc, (Do Not Recommend for first time builders) to use. I had part fitment issues, had to order new parts to work and then return parts that didn't. Otherwise I like the case and does Great for Cooling. Read more
