I have Cooler Master Storm Rapid I mechanical backlit keyboard. It's pretty compact as it doesn't have numerical keyboard. It has nice light effects as it pretty configurable. I am not really impressed with this keyboard - I make a lot typing mistakes, it's very sensitive. For comparison, I can type faster and with fewer typing mistakes on Lenovo e325 laptop keyboard. It costs about 100euro in my country.

I don't have experience with other mechanical keyboards, so i would appreciate if someone can compare it to other mechanical keyboards.
