Hi, said I’d give feedback somewhere regarding the build I started as of this evening using 690 case, must say it’s a cracker! I'm even considering ditching my Antec 182 for this; as the airflow is excellent and on par with Antec 900, minus the 900's ugly look.

I’ve only found reviews of 690 using just the three fans supplied, cooling was decent but nothing stand out special, however this case will house 7 (yep seven) 80,120 or 140mm case fans, so I put on seven 120mm, 1200rpm fans and the idle temps im seeing using a Q6600 are just a tad good (Dropping back to just 5 fans, 7 is overkill tbh yet its still quiet).
No rattles, very low noise levels too, if this case cost £70-£80; then I’d suggest you look elsewhere as there's plenty around that price point to choose from, but for £50 you will be hard pushed to find a better case suited to over clocking, great cooling and fairly solid too. Granted you will have to use a few extra fans to get the most out of it, Cooler Master should have supplied 5 and not 3 in my opinion (Imo 2 on top, 1 back, 1 side, 1 bottom), but then most of us will have case fans that can be transferred over considering its able to house 80, 120 or 140mm fans on all mounting points!
Mates going to be well chuffed when he comes to collect on Sunday, once all done.

Feel free to ask any questions or more info regarding the case; I’ll do my best to answer whilst there's still one sitting under me desk.

Edit: Will add some pics to the thread when i get time.
