I've got one!
It's MASSIVE! like, way bigger than anything you could comprehend as apparently a keyboard. It doesn't only come in browns, mine has blues - TacticalStache, literally, where do you get your information from?!
It has a built in soundcard, that is about as good as you would expect a soundcard built into a keyboard would be.
has a powered usb3.0 hub in it though, which is quite cool. And - it's fully programmable, I don't know why coolermaster don't make more of a big deal about this. it has 5 programming layers, and each one you can set each key to be whatever you want, excluding numbers 1 - 5 as these are used in changing the layers.
I think the usb hub and the programmable-ness of it are cool - though, the Trigger-Z is also fully programmable, it's not as gigantic, and it's a bit of a aesthetically nicer keyboard, imo, and is a better choice. Though the Trigger-Z still has a funky space bar even though the rest of the layout is standard, so it wins over the MECH on layout too.
