I've reviewed that keyboard. Surprisingly, for a rubber dome keyboard its pretty good. Key caps are better and the backlit is well balanced. I didn't really like the mouse. I found it uncomfortable as a palm user, especially if you have large palms. CM said that they wanted to keep the mouse as low profile, but part of the mouse had that bit sharp corner that wasn't really comfy. Claw users wouldn't be affected by it.
I really hope CM sells keyboard as a standalone unit. You should know that it doesn't have 6KRO/NKRO support. First 4 alphabet keys can be crunched at the same time but other than that it either 2-3 keys, except CTRL key combos. I am not sure logi G105 or even razer's bundle in the past had similar thing, but you can check it out. Not sure of corsair since the boyz and girlz in India aren't really open to feedback and criticisms.
