Thanks for the info. I think there's a misprint in the manual, then, since it shows installing 140's on the outside.
Sorry CM MR HAF but I see and feel no difference in strength anywhere on that panel by cutting those tabs like others have already done with easy success. The manual probably cost users possible wasted additional $$ for ordering 140mm fans they thought would fit per the manual photo above and now they either will have to mount them inside that some may not want or put out additional $$ for other 120mm fans if they don't want to mod the panel.
Here's my comments as I said I would early:
Well being I received the fan order late yesterday I went ahead and tried my method this afternoon with the Yate Loon 140mm fans. Not doing my brothers build yet as I'm awaiting the fan controller.
What I did was with fishing line tied the upper fan frame to the upper case crossframe to keep it up without screws, then placed the front panel totally on. Okay don't get excited, the front panel goes on fine without the fans screwed in but however I was able to ascertain the discrepancy. The problem is that in order for the fan(s) to be screwed in the hole it needs to be approx 2.5mm higher from the center of each fan screw hole. I was able to push down on the fans from the inside of the chassis with VERY little give and you couldn't forcefully line them up if your money depended on it.
So either Cooler Master royally screwed up if they meant of 140mm fans to be mounted in the same place as the 120mm fans which came installed with the case or they only meant 140mm fans to be mounted in the inside of the chassis which there was no indication from Cooler Master about this which to me is another screw up as nobody knew till they tried installing 140mm fans themselves.
IMHO Cooler Master should offer people with this case a free updated front panel that corrects the issue so to easily install 140mm fans there, that is if it was meant to be mounted there initially.
I'm still hoping we get a response here in this thread real soon from Cooler Master about this issue, I already PM'ed a rep and maybe some of you can try to get a response from them as well. I think we all need closure with this issue which again should have been explained when they said the front can fit 140mm fans IMHO.
Added edit: After discussing the front fan situation with my brother and showing him he's going to opt using 120mm fans in front and I might follow suit as well. Now to order 120mm Yateeeees lol!, but probably will wait till Monday in case of Petra's promo's.
In all honesty I believe it is easy to see that the 140mm's need to be mounted inside. If you intend to run 140mm's on the outside it is not difficult at all. All you have to do is trim the plastic that juts out . I used a dremel and it took me 5 minutes.
Well since that post you referenced and by the posts afterwards convincing me to cut and I so did this morning. The difference in strength and rigidity by doing so = no difference. It "flexes" no different than before doing it or any difference in panel rigidity by the front I/O compliments. Now the 140mm fans sit nicely in front.
