★★★★★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.

★★★★★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.

★★★★★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.
