Just received one and built a system. Brings back memories of early/budget cases where cost savings have somewhat affected the build quality so there's some misalignment in the motherboard standoffs for example though it is very slight. The screws go in just maybe a bit tighter than other cases oh and tighten to hand tight plus a bit or you'll easily over tighten and spin the fixings
The PSU shroud is fixed and so are the drive mounts. That means longer modular PSUs will be a struggle to plug the wires in. So I would leave the PSU out of the case and only push it in place after installing all the power cables. Short PSU not so bad. I have tried both.
Lastly the RGB fan controller hub has no fan speed control. This may be a big issue if you want a quieter build as all 4 fans run at full speed. They aren't actually that annoyingly loud more of a constant rush of air. Lian Li use a similar hub in some of their cases and that has a rudimentary speed control via a fan header just not with RPM feed back.
That penny pinching decision may be the reason not to buy this case honestly.
Once built though the case performs and looks just as good as cases costing X2 or X3 times as much due to the RGB fans and tempered glass front and side. Cases with a solid front whether plastic, aluminium or glass will always suffer somewhat in the cooling and certainly if you mount a rad in the front so this case is no different from the many that do this.
OCUK please get Kolink to add the basic fan speed control please as it doesn't seem like much of a difference until you want it! The hub appears to be made to do this but lacks the slight wiring change to the power cable + fan header.
