See? I told you people, and was laughed at. Now that it came from the horse's mouth (Jim, you're not a horse... though I'm sure the ladies call you a Stallion) I hope you people take what I said more seriously...and bash your hand with a hammer for doubting me.
The gap is there for people like you to ask questions about, and people like us to give you silly answers.
1 Main reason...
So you can remove the motherboard tray with the motherboard still attached to the tray. Notice how the gap is equal to the Clearance needed to get your in-puts and out-puts away from the I/O shield and lifted out of the case.
Yes it promotes air flow and yes you can run cables through it but those are secondary and if you jam it up with too many thick cables you wont be able to safely remove the tray and motherboard. Edited by Maxxa - 5/5/11 at 8:36am
I am actually surprised at this, but i can understand why and hey, I would rather add bits to the case than have to cut it up Any chance of an option to get cases without the gap by any chance or would that cause problems in production?
in another thread, Jim mentioned that custom pieces and parts are kind of a no go right now for production reasons but may change in the future. But an email or PM to Jim about a specific request may work out for you too . . . doesn't hurt to try it.
