Cooler Master CM 690 III USB 3.0 Midnight Black Mid Tower Performance Computer Case with Side Window + USB 3.0 w/o PSU is rated 4.0 out of 5 by 2.
Rated 4 out of 5 by from Great Case, need to check suppliers. I bought 2 of these from Scan, as they were by far and away the cheapest. Unpacked them both, on one the window perspex had come away from the side panel, upon closer inspection we found it hadn't been fitted. No dramas, the lugs hadn't been bent over the perspex, so carefully did this and presto! Back in business. The other case didn't have the rubber grommets over the cable management holes, whereas the one with the window issue DID have the rubber grommets on all of the cable management holes. Aside from those 2 niggles, building inside it is a breeze and can thoroughly recommend this case. Do these come from different suppliers?

Rated 4 out of 5 by from Good Case Let Down but Poor Fans Supplied I have recently built using this case and it was a pleasure to build with but I would note that the 2 fans supplied are very low end and both only 3 pin (non PWM) Coolermaster make 2 types of 200mm fan that look identical. these are 700 and 1000rpm. The one supplied is 700rpm (hits about 750) - this feels like a cut corner. I have also purchased the 1000rpm fan seperately (hits over 1100) which looks no different and is no louder. The 120mm rear fan is also of very low specification, it only hits 1100rpm which is really bad for a small fan. The standard coolermaster fans (blademaster 120) hit just under 2000rpm and again are identical. I would buy this case again as I like the look, but I would also buy some extra fans to replace the ones supplied

I am reading conflicting reports including on this page regarding whether this comes with grommets on the cable management holes?

Can you please clarify for certain whether this comes with grommets on the cable management holes or not. One person answered that it does and one person answered that it does not.
